    Yep, but still illegal to fit HID bulbs to projector housing's that were supplied by manufacturer with halogen bulbs. Strange I know, but 'tis the law here.

    https://www.nzta.govt.nz/resources/g...-lights-right/

    "High intensity discharge (HID) conversion kitsHID conversion kits (an HID bulb with a high voltage power unit or Ďballastí which fits into the original headlamp unit in place of the original bulb with no change to the headlamp lens, reflector or housing) are illegal on any vehicle being used on New Zealand roads.
    However, a complete halogen headlamp unit can be replaced with a complete HID headlamp unit provided that the replacement headlamp unit complies with approved standards. If in doubt, get advice from a vehicle lighting retailer you trust."

    Sadly, it's the one of the first things they look for when conducting a WOF (warrant of fitness - regular vehicle inspection - every six months for a 10 year old+ car). Mainly because there are a lot of young fellas and gals that modify in ways that are just awful for other road users. As usual, one size fits all when it comes to common sense.

    I will never complain again about Cali smog check every other year =)

    Yeah, it can be a pain but if you keep your care well it's okay and the inspection only costs about US$30 each time. Ironically, because it is an old car, I am not required to meet current emissions standards (nor in fact, the standards at time of manufacture), so my car happily runs on a custom catless exhaust!! The inspections is 100% about vehicle safety rather than the environment. Always feels like a missed opportunity but it least it means I can keep my v12 on the road, I just rely on my own environmental guilt to not drive it every day!

    Projector housings for halogen bulbs have completely different optics not meant for the much higher lumen output/orientation of an HID bulb though, so I understand the argument motor vehicle regulation boadies have--we have something similar in BC. The E31 projectors are amazingly good though, considering their time, but many halogen ones can't contain glare from the much brighter HID bulb and get bad hotspots in the beam pattern.

    That said, I have a set of Lexus RX350 projectors I have put aside to fit into the E31 housings once I get around to it...

    Thatís not entirely true. The main difference is where the bulb mounts to the projector itself and the style of base. But with aftermarket HID bulbs, or what are called "halogen rebase" bulbs, the HID optic is designed to be located in the same position that the halogen filament is in so that the output pattern and hotspot is correct and in the correct location just on average 3 times brighter.

    Glass wise for the optics is usually the same, just maybe a different focal height to adjust the output.

    The problem is the same for LED's as it is for Xenon's - there will be a bit of light scatter above what there normally is as neither can imitate the tungsten element. But, it would be a pretty switched-on tester that noticed either modification!

    True about rebase bulbs. But even then, only for the *best* rebase bulbs, but the vast majority of aftermarkets are not manufactured very well. I've had to shim even the Morimoto XB to get the hotspot placement correct and some playing around with rotation is often required.

    Led & hdi

    All

    Two weeks ago my yearly MOT in the UK was due during the light test the examiner told me my HDI low beam will fail the test after May this year on car where the HDI fit was not standard fit.
    So looks like the LED bulbs will need fitting for the next test to pass.DSC01341.jpgDSC01341.jpg

    Yep, of course. But in the unlikely event of an accident, your insurance would be voided. Would prefer to have some legal that is better than stock halogen!

    This type of behaviour is for ricers, not gentlemen that drives eight series.

    No itís the type of behavior that allows someone to do what they want to their property and ignore a meaningless government regulation. I donít think you know what a ricer is.

    Yes and no. You will need to read the post from the beginning and draw your own conclusion. There is talk of flickering, thermal resistors etc.

    Would like to give an update on these, so far I have been extremely satisfied with this upgrade. I did have to add resistors because of some error messages and flickering. I mounted outside the headlight bucket because they were getting quite hot. Resistors are plug and play. So the entire system works very well and the difference in light output is night and day.
    Link to the resistors that need to be purchased with the lights: https://www.amazon.com/dp/B06XX5KTMF...iglink20399-20

    Thanks Dragon, as always, excellent information. The problem is you are expensive to follow. Keep up the good work.

    Yep had replace shocks. Also everything was loose snugged up and shock. Ready for spring.

    Timm, at the bottom of the article it says "Parts and Tools Used" but nothing is listed. I don't find a link to the PTC specs.

    I was actually blown away by the result, its as bright as factory xenon on my Porsche Cayenne which I think are exceptional.
    A small tip, in order for the bulbs to fit the headlight has to be adjusted all the way down first, the bulbs have a fan on the back.

    I just did this, waiting for it to get totally dark out to see results, but they look great on the garage wall. Thanks for posting this, its an excellent upgrade over the stock bulbs.
