    Smile DIY For BMW Cup Holder & Console LED Lights (Pictures)

    BMW Cup Holder and Console LED Lights DIY (with lots of pictures)

    DISCLAIMER: I did this in my 1995 318i E36 using the 1996-1999 style E36 Modular Cup holder/Storage Tray/Coin Box Console. However, the ease of the DIY makes it applicable to any other BMW from any years, as well as other brand vehicles that come with similar style cup holders and consoles. It is a monster write up for what is basically a quick, simple and cheap DIY with a highly OEM cosmetic and functional appeal.

    INTRO:
    If you ever did an extended road trip where you have long stretches of highway to cover after dark and your only passenger is a cup of coffee and you often had to fidget to place the coffee in the miniature E36 cup holders and often end up spilling some of it, then this easy and cheap DIY is for you. Even if you want an easier time finding stuff like keys, money, credit cards, etc... in your Storage Tray or Cup Holders at night whiles driving then this DIY can also work for you.

    BACKGROUND:
    Iíve been meaning to do this for sometime now, but needed to find the time and the best method of installing cup holder lights in the console area. Originally the idea came to me a few years ago when I first discovered my car had wiring beneath the console for a Telephone, Aux Audio Input and a small filament bulb that I assumed was there to light up the console area.



    Naturally, after 10+ years in the car the bulb was blown so I went to the dealership to replace it hoping that I could have use the light for my cup holder. BMW wanted $12.50 plus tax for what is nothing more than a single Christmas Tree light bulb (that you can normally buy for 99 Cents for a box of 100). I said no to them and started thinking of another way of doing it. I went online...

    Over the years I found a few DIY sites showing different methods, the best was this one;

    BMW E46 Illuminated Cupholder DIY

    Here this guy installs two 20mm disc LEDs into each holder in his 2004 325xiT wagon. This method is very OEM and clean looking and was my first choice. Sadly, the 20mm LEDs he used proved near impossible to buy since the USA company that imports them from China no longer exist. So short of taking an airplane to Shanghai that DIY was not going to work for me. Also the guy used a Dremel Set and spent time soldering the complicated micro LED circuitry to finish off his project.

    There are a few more Cup Holder LED Light DIYs at the Honda Civic and Dodge Charger Web Forums that show folks hot gluing smaller 3mm - 5mm LED bulbs (from 2 bulbs up to 10 bulbs) into tiny holes drilled into the console cup holders. And Electric-taping the wiring together under the 12V outlet. Although their techniques were sloppy, the idea of simple wiring with smaller holes and LEDs was cheaper, quicker and more flexible for me. Also messing up didnít mean having two big 20mm holes to worry about in your console.


    DIY PREP:
    So I went on eBay and purchased a set of twenty 3mm Orange/Amber LED complete with wiring from a Hong Kong company called Sure Electronics. They ship within 2 weeks, but their LEDs were quality and the entire set worked. (you will hear from some people that LEDs come not working) The LEDs cost $9.99 total with shipping. I also purchased 2 spools of 20 Gauge wiring in RED and BLACK colors from Radio Shack for $6, as well as Heat Shrink for $3 and wire connectors for $1.99. I already own a power drill and Crazy Glue was the only other expense.


    My 1995 BMW 318i came with the older style E36 Cup Holder which sucks because not only are the cup holders extra small and useless but everything is stationary so you cannot move the coin holder and cup holders around like you can on the newer 1996-1999 style E36 Modular Cup Holder. I wanted bigger holders and a storage partition instead of an ashtray so I went back on eBay and won a brand new E36 Modular Cup Holder with Storage Partition for $50-shipped. I then managed to sell my old one on eBay for about $50. So I broke even.

    Here is a Before picture of my 1995 early E36 style Console




    That said this project only cost me about $20 to $25 for the LEDs and wiring and crazy glue.




    TOOLS:
    Power Drill w/ 2mm or 3mm drill bits
    Small philips star point screw driver
    Crazy Glue
    Wiring Stripper/Crimper or Scissors

    EQUIPMENT:
    Spool of RED 20 Gauge wiring
    Spool of BLACK 20 Gauge wiring
    Heat Shrink
    Wire Connector Clips (2 sets)

    THINGS TO HAVE NEARBY:
    Your Carís Battery or a 12V Battery (for testing the bulbs and connections)
    Small Needle Nose Pliers
    Scotch Tape or Electrical Tape (for temporarily holding the bulbs in place whiles the glue dry)

    THE REST:
    The Modular Console Base w/ Cup Holder Modules and Coin Box($99 at the dealership or $40+ on eBay-if you buy a used one off eBay just make sure the cup holder modules' 4 spring grip finger slats for holding cups are all still in place since usually they are sold with one or two broken off. If you get a broken one you can easily replace it by buying new cup holder modules which cost about $15 each at the dealership)


    The Storage Partition Tray w/ Parts Number in the picture ($14-$18)


    Set of 20 3mm LEDs ordered for $9.99 w/ free shipping from Sure Electronics in Hong Kong via eBay (they also sell under the eBay Seller's ID: eylane). The important thing is to make sure the LED bulbs are pre-wired with power (RED) and ground (BLACK) pigtails. Also stay away from Aftermarket Brands and Auto websites selling these exact same bulbs minus the wiring and nothing else in expensive "LED Kits" that cost $25 to $40 for 5 bulbs.


    LETS BEGIN:
    1. Begin by removing the two Modular Cup Holders and Storage Partition tray and The Coin Box as well. If your Modular Console came with the Ashtray then you can buy the Storage Tray on eBay (I got mine there for $14.00) or the Dealership for $18.



    2. Find the 4 finger slats that spring-grip the cups and look at the space right below each one. Here is where you will drill your 2mm or 3mm holes. I put holes under each slat (four slats, four holes, four bulbs) to balance it out, but you can only drill less holes if you want to use less bulbs. During the project I realized that 4 bulbs may come out brighter than I wanted or stick out and be obvious, but because the 3mm bulbs are tiny and the way they are placed under the spring-grip finger slats they bulbs donít stick out and the light emitted from each bulb doesnít shine above the console-meaning it wasnít bright or harsh at all, but just right.





    3. After drilling the 2mm holes, you can used the screw driver to widen the holes just a little bit to squeeze the 3mm LED bulb thru. Too small is okay but you donít want the hole too big. So be careful if you use a 3mm drill to not to let the hole be bigger than you want. Also the bulbís shape is similar to that of a Bowlers Hat, where the top is round and then the base of the bulb is wider with a slight brim or ledge. This is good because you can squeeze the 3mm bulb into a smaller 2mm to 2.5mm hole and not have the bulb fall thru into the cup holder.







    4. After you do the Cup Holders you can start with the Storage Tray Partition. I only drilled one hole and used one bulb, but you can use more if you need to. Center the hole and begin drilling.

    5. Connect your wires. For the first Cup Holder connect all the RED wiring and Heat Shrink them to a 12 inch strip of RED wire from your 20 Gauge spool. Then do this for all the BLACK wiring as well. Test at the 12V Battery to make sure everything works. Then repeat for the second Cup Holder. When you are done you should have two sets of RED and BLACK wires that power the two Cup Holders. Test everything on your 12 V Battery. Now do the Storage Partition. I only had one bulb with a RED and BLACK wire from the Storage Partition. I extended these two wires with a 12 inch 20 Gauge RED and BLACK wiring via a Heat Shrink. Test with a 12V battery.
    Now you should have three sets of RED and BLACK wiring; the Cup Holder 1 set, Cup Holder 2 set and the Storage Partition set. Splice all the 3 BLACK wires together and Heat Shrink it onto a BLACK 6 inch wire from your 20 Gauge Spool. Do the same for the RED set. When done you will have only one RED and one BLACK wire that powers both Cup Holders and the Storage Partition. Test them on your 12 V battery to see that everything works.













    6. Splice All the RED wiring and BLACK wiring together onto one branch that will connect to the POWER and GROUND wires under your console. This part is pretty straight forward If you just picture the branches of a tree coming together at the trunk. I found heat shrinks to be very easy to use and quick for this DIY. Be sure to keep testing at the 12 V Battery to be sure everything is working each step of the way. LEDs are pretty durable and long lasting but you never know and you don't want to finish a project and flipping the switch to see only half your bulbs light up. When done you can test everything again at the Console Bulb's power wires found under the console. Just insert the tips of your RED and BLACK wire into the tiny holes of the bulb's harness socket. One wire will be red/grey for power and one will be brown for ground.












    7. Glue time! This was really the hardest part; deciding the best glue to use. I didn’t want to Glue Gun the whole thing because that looked very messy in the other DIY that used that technique and also I’m not sure how easy it would be to change the bulbs or reverse the project after you spackle the whole thing with huge gobs of plastic glue. I decided Crazy Glue was the cleanest and quickest way to get the bulbs to stay where they should. Also it would be easy to pluck out the bulbs when and if the time came since I only used a tiny drop of glue for each bulb. Start with the Storage Partition since it is a square, flat object and easier to see what you are doing. Put only a drop on the bulbs brim (close to the base right before the wires) and wedge it in. Use the tape to hold the bulb in place. Then do the same with the Cup Holders. With these the tape is necessary since the web of wiring will all pull and tug every time you move to another bulb on the same harness. Give yourself time to make sure the bulbs are well secured. Allow 20-30 minutes for the glue to properly dry.

    8. Wire Connectors! Apply the 2 female connector leads each to the RED and BLACK wire coming from to your Cup Holder and Storage Tray. The female connector leads are tricker to apply and I rather do this with the RED and BLACK wires from the Cup Holder and Storage Tray inside my air conditioned home. When done with the female leads go the car and find your console bulb. (Most E36s have these old school filament bulbs under the console that was factory wired for an Ashtray Console Light and if your car is over ten years old chances are this bulb is already blown. My BMW dealership wanted a whopping $12.75 for the replacement filament bulb, which is how I decided on this DIY to begin with).
    Snip the wires that power this bulb (one should be Brown for Ground and the other Grey w/ a Red Stripe for Power) and apply a male connecter lead to each wire. The male leads are way easier to apply hence why I saved them for the car.









    When done, go back inside to your Cup Holders and Storage Tray. The glue should be dry by now.

    9. Reassemble the Modular Cup Holder 1 and 2 and the Storage Tray Partition into the Modular Console base frame! Okay, STOP! This bit is important; if you made it to this step and you begin replacing the newly wired Cup Holders and Tray back into the Modular base frame you will quickly realize that it appears that the Modular base frame's section cross bars and all the wiring prevents you from getting them back onto the Modular base frame and now you are wondering why you didn't glue the LED bulbs/wires onto the Holders and Tray after reassembling the Console. Don’t panic, like I did, because this is good thing and the wiring really does not prevent you from replacing them into the Modular base frame. If you had glued the bulbs onto the Cup Holders and Storage Tray after you reassembled the Console then the wiring would have definitely prevented you from getting the modular parts off the base frame making the process of customizing your console or removing a modular part of the console impossible.
    All you have to you have to do is make one end the front (where the Cup Holders go) and the other end the rear (where the Storage Tray Partition goes).

    A. Starting at the front end hole slip the Storage Tray sideways through from the top all the way out through to the underside of the base frame. Let all the wiring follow.

    B. Now bring the Storage Tray back up thru to the top at hole at the rear end and connect the Storage Tray in it’s place. All the wiring for the Storage Tray should be under the Storage Tray and going from the bottom of the StorageTray to the first hole front end and up thru to the top where it meets the Cup Holders.

    C. Now insert the first position Cup Holder and let the bulk of wiring for it sit at the bottom right below it. You will see that there will be only two wires (RED and BLACK) left that join the two Cup Holders and you can easily run these two wires between the cup holders above and in between the Modular base frame's cross bars.
    D. Now insert the second position Cup Holder with the bulk of it’s wiring sitting below it and the two wires running above the base fame's cross bars. Now insert the Coin Holder. All the wiring should now be beneath everything.











    10. Return to the car and connect the male and female leads. The reason I used snap on connecters here is so that at anytime in the future I can easily disconnect the lights by simply unplugging them. Test the LEDs again after you make the final connections. Now replace the entire Console back down in its original place and make sure all the wiring is underneath the console and none of the wiring is pinched. Since you used 20 gauge wiring like you should have all the wires should easily fit under there.

    11. Turn on your car and turn on your Parking Lights. Your Cup Holders and Storage tray should now be glowing a glorious amber like the rest of your BMW dash. NOTE: You can dim the Cup Holder and Storage Tray LEDs with the Dimmer Switch found on your lower left Dash Board. This is good to have because if you use your parking lights in the daytime you can turn down the LED brightness and energy consumption. (Not that they consume lots of energy to begin with). You can also easily install a small rocker switch ($2 at Radio Shack) at the male/female connector leads if you want a separate switch for the Cup Holder and Storage Tray lights.












    12. Daytime shots. You can still see the amber LEDs in daylight but it is not distracting at all.







    13. Nighttime pics. The Amber really comes alive and matches the OEM Amber of the console. The first thing you think after seeing this effect is why didn't BMW think of this to begin with. The convenience alone is awesome, plus it is very visually impressive and not overwhelming. Also you can easily add a small switch to the console to turn them on/off if you eventually find having them on when you are not using them to be a bother.

    Pictorial DIY BMW Sunglasses Holder Space & Console LED Lights (Part 2)

    13. After installing the cup holder LEDs and my new 18 Button OBC.
    The empty space beneath the OBC seemed rather dark and impenetrable
    so I decided to add some LEDs in there. This was fairly easy and it only involved removing the OBC and Sunglasses Holder Sapce/12V Lighter Element and splicing into the Grey/Red power wire and Brown ground wire that goes to the small filament light bulb that lights up the Cigarette Lighter Element ring.

    After your splice just run the LED wires behind the Holder and tie wrap it to the vents. If you are working with 3mm LED bulbs then the bulbs will just click into the vents. Line them up so they will be even and the light coming from them will shine in the space evenly. When they are inserted just apply a drop of crazy glue to hold them there. Alow 20-30 minutes for the glue to properly dry and put everything back in place.

    The results should be nice.
    Pictures below;
























    14. As you see here during normal driving at night the LEDs don't glare up above the rim of the cup holders so it is DOT safe. I also upgraded my 7 button MID/OBC to the 18 button OBC that same day. Unfortunately, during the process I broke the smal lfilament light bulb that lights up the orange ring around the Lighter Element so I ended up having to buy a bulb for $12.50 from the dealership after all.

    They also have BMW Coffee, BMW Apple Juice, BMW trail mix/peanut packs (like you get on the Airplane). And to think I overheard some snobbish people complaining that either the Mercedes or Bentley Dealerships have chilled Champaign and Caviar in their waiting rooms.

    Anyhow,
    I got two more DIY coming next.

    1. The Complete Pictorial DIY Guide to the 7 Button MID/OBC upgraded to the 18 Button OBC. I just did this and I'm writing it up right now. I just ot a few more wrinkles to smooth out before I finish (like finding the ZKE IV Module, Installing the BC Stalk and Finding out if I have a CCM)

    2. DIY guide for E36 BMW Alternator exchange (Taking it out and putting it in). I did this a few weeks ago and it was a PITA only to have the $99aftermarket one die on me a week whiles I was miles away from my hometown and I ended up buying one from the dealership $385 and paying some really nice guy in a town far away $140 to change the old one.

    3. I also have to finish the BMW E36 LED upgrade (Rear footwell LEDs, Rear Armrest Cup Holder LEDs, and Door Open LEDs with Door Handle Find LEDs)

    4. Then I have to get back to finally finishing the ICV clean I started a month ago...before I ran into my Alternator woes.

    like the ingenuity. would like to get one of those consoles for the drinks holder. might have to be careful wtih those leds so you don't damage them when taking things in and out. i wonder if you could get little ccfl rings in the bottoms there in the amber colour?

    well done anyway for an interesting mod!

    i think you have to be careful with cups too, making sure that drink doesn't spill on the led's. maybe seal them up? i am interested in this aux in that you found, can you tell us more about that? would love to be able to find a way to plug in the ipod into the car system. i have a kenwood with ten disc changer. maybe i can get an aux into the changer box somehow ..

    "I took like 5 bottles since I was already paying $150 for a simple Coolant Flush and Replace". why take two bottles into the shower!

    i am going to raid the dealer next time i go! last time i went in, i got some nice postcards last time! whist there i got four bottles of coolant, that's 6 litres of the stuff. i'd better make sure i don't mistake the water bottles for coolant bottles! while i am there, i might just get the fan clutch removal tool to save me from snapping my screwdrivers .. hey simon, next time you're in london, let's go to the bentley dealership and eat and drink for free! lol!

    I like the outcome and professionalism of TMK's DIY as well, but 20mm LEDs are rare and hard to find outside Hong Kong and when you find them they will cost $$$. Plus I don't do Dremels and Soldering in my car unless its life or death necessary. I love my baby too much. Nevertheless, TMK has some really great DIY ideas on his website similar to the sort of things I like. I totally recommend his website for anyone looking to improve their BMW.

    LEDs are water resistant/proof. Or at least more so than other lighting elements. Also they don't heat up like filament bulbs so I'm not worried about cool liquid condesation from drinks getting on them.

    I also have a Kenwood HU and the Aux Audio plug seems to be connected to the HU, but in the last 4 years I have never figured out how to use it or why it doesn't work. I believe the answer is in the HU and I'm pretty sure before I bought the car the HU original came with a remote control that had the button functions for switching to an Aux Source since I can't seem to find any control for Aux input on the face of the HU. Also the lack of a manual doesn't help. But I have my Sirius Satelitte Radio hooked up to the HU so I never found use for another source of music in my car,

    My soon to be replaced Kenwood HU....

    here's a tip. i found a din cable that turns your cd changer input into an aux input on ebay from hong kong. i might give it a spin, for 8 quid inc. postage can't go wrong! i have quite an old kenwood head unit, but if i can make an aux in out of it, then i might as well stay with it for now! i would have to somehow get that aux cable back out into the cabin tho ..

    I've spliced and added a second LED to the rear side of the Storage Tray because it looked dimmer than I'd like with just the one LED bulb in there.

    Cool Pictorial DIY BMW Rear Armrest & Cup Holder Console LED Lights (Part 3)

    Pictorial DIY BMW Rear Armrest & Cup Holder Console LED Lights (Part 3)


    Hello again,
    This will be the final part of my 3 part BMW Cup holder Console LED Lights DIY project. In this section we will continue by adding a LED chip to the rear fold down armrest/cup holder. The effect of this DIY is really clean and impressive;



    This DIY will only be accessible for those with BMW 3 series that have the fold down armrest in the rear seat. If you don't have this feature and really want this DIY then I suggest checking out eBay or a local yard for the rear seat. At this day and age they are not too expensive and should run you between $50 and $100. Plus if you have a leather cushion seat all you would need is the back cushion in which the armrest is embedded.
    If you find yourself lost in this DIY you can easily refer back to the earlier parts where I describe the tools and wiring needed as well as what power sources under your dash and console to tap into. Also the LED Chip used is an Aluminum-Based Board 1206 SMD LED Cluster White 201 and was purchased from the same Hong Kong Company Sure Electronics via eBay. They sell thousands of these LED Chipsets varying in color, intensity and Chip size. I got one with 8 LEDs at a cost of 99 cents plus $3.99 to ship. I will post the detailed specs of the LED chipset at the bottom of the DIY. That said, the pictures should be easy to read and follow if you don't like reading words.

    1. Begin by removing the rear armrest from car. It is anchored in two metal socket slots at the point where it pivots. Tuck your hands under as you pivot the armrest down and lift the entire thing up and out the sockets. Once out, take the armrest inside to begin modifying it.






    2. Remove the black plastic back cover. It is anchored by 8 clips that pry off. They are not super firmly anchored but if prying off with a hard or sharp object go slow so as to not tear or damage the leather skin of the armrest. Pry all around the edges repeatedly until it pops off. Underneath you will see a metal bar that connects the pivot joints and another plastic covering aka the back wall.









    3. Drill two holes in the back wall. One hole will be for a power wire and the second for a ground wire. The reason for drilling two tiny holes instead of one big one should be apparent as you will need to pull each wire thru its hole. I also ran out of black (ground color) and red (power color) 20 gauge wire so I ended up using the green color that was left over from my other DIYs for both power and ground leads. Because of the high chance of error in mixing the wires two holes are better than one.




    4. Inside the storage space of the console you will see a small rectangular/ square-ish hole at the top of the back wall. Make a note of it as you get yourself a wire coat hanger or long piece of skinny wire that will fit thru the holes you just drilled. Extend out the wire coat hanger so that is is one long rod and begin pushing one end thru one of the holes. The console storage space should be open and you should have a finger at the rectangular hole feeling for the end of the hanger. When it come thru pull it out so you can see it. Attach the end of one of your lead wires to the rod (I used heat shrink and some crazy glue for this) and pull it out back thru the rectangular/square hole and the hole you drilled. Then repeat for the second lead wire.

    5. Begin drilling anchor holes for screws for the LED chip. This is optional as you can use glue to anchor the chip or a similar adhesive like Velcro. Remove the Slider Cup Holder trim; it easily pops right off from its rails. Drill two holes and use small two small screws that will hold the chip in place. It is really tight in there and if you have big hands this is a good time to have your girlfriend, wife or a small child help you with the screws. Either way glue or similar adhesive (like using a Velcro kit to hold it in place) will work the same and be easier.










    6. Splice the LED chip + and - wires to your power and ground leads. I used a clip in/clip out connector so I can easily remove the LED chip from the wires if I need to change the LED, remove the armrest or remove the DIY from the car in the future. You can use heat shrink, solder etc....
    Just keep it safe and clean. Also feel free to use inline fuses as well. I did not use them for any of my Console LED DIYs because the power sources that I tapped into already have safety fuses. Also genuine LEDs consume little power and usually burn cold, unlike the hot, energy-consuming filament bulbs used thru out our cars). The LEDs that are installed in these DIYs are water resistant and fire safe. That said if you have any further safety concerns or intricate questions about LED bulbs or the basic wiring used in these DIY please consult an electrician before attempting them.







    7. When the LED chip is set and all the wiring is complete test your set up at the car's battery or any 12V source. If everything works then you can replace the rear cover making sure the 8 clips all click back in. Be sure to leave some extra length of wire in the sliding space behind the console storage or you will find the short wiring doesn't allow the storage tray to slide all the way out. At this point make sure that the tray, as well as the cup holder slider move freely without any blockage from your LED Chip or wiring.

    8. Return to your car with a pair of really long 18 or 2x gauge wires. In my DIY these are the two red wires. I cut off about 8 feet each but ended up only needing 5-6 feet each. I used 18 gauge only because the wire is thick and firm (like a wire coat hanger) and was easy to manipulate and push thru the many crevices and layers in the car en route to the rear armrest from the Cigarette Lighter Element' bulb tap in point under the front console. Run these wires to the rear seat cushion and splice them with your leads coming from the LEDs. When done tuck away all the wires under the seat cushion and turn on car.

    When you open the Cup Holder Storage Tray the LED Chip should come on and be alight with glory.







    ADDENDUM:
    You can easily vary this DIY by using your own version or color LEDs. Just make sure they are genuine LEDs. The technique for doing this should be the same for all E36 cars as well as other cars with a similar electrical and interior layout. If you want you can also easily add a switch for the light or add extra LEDs for rear passengers using your power/ground leads coming from the front of car. Just having the extra leads back there will give you the flexibility to add other things you may want to have in the rear of your car.
    Here are the specs for the LED chip used in this DIY:

    Nice writeup, I like the way it came out.

    Is your shifter on backwards?
