    Picture gallery of the euro OEM ZKW vs OEM Bosch lights

    I've been searching for a while for a set of real OEM euro lights. In the search, I found it very hard to get actual pictures of E36 headlamps that arent either depos, or modified with HIDs/AE/etc. I really wanted to understand the difference between the different brands, aside from the modifications you can make to them.

    I've now had the opportunity to get a set of very clear photos from an ebay seller based in Germany and will attempt to illustrate the differences here

    Let's start with the front end.

    These are the Bosch headlights



    These are the ZKW



    Differences in the front
    • ZKW's have a striped glass pattern on the bottom half of the projector. I'm not sure what you call this pattern
    • ZKW's have nipples on the top glass
    • Bosch have a more pronounced pattern on the inner headlamps
    • Bosch have three tabs on the top, ZKW have two


    There are several differences on the back.
    Bosch


    ZKW


    Differences
    • ZKW dust caps are squared
    • ZKW dust cap clasps appear heavier duty
    • ZKW have larger clamps holding on the front glass



    Bonus: OEM tabs can break too, be careful people



    There are many more pictures if you want to examine the full gallery here. Note, the Bosch headlamps are the first in the gallery

    Anything else anyone wants to add? For example, light output, beam pattern, cutoff, etc. I havent had time to install these ones yet

    The "striped" glass is called fluted. It actually is bad for a projector as it robs output and it scatters the light.

    I might be stupid for asking this, but what's the deal with the nipples on the top of the glass? They seem to be a positive selling point for aftermarket lenses on ebay. What is their purpose?
    Yoy.

    My research indicates it's a personal preference... looks

    As mentioned, some versions of the Bosch have two tabs while others have three. Some of the Bosch headlamps also have velocity nipples.

    From what I've found, the older version typically has 3 tabs and no nipples.

    So is Bosch preffered ove the ZKW's? Can HIDs be installed in either set? What's the light output like in both?

    Just FYI, I only deal with Bosch because nothing comes close to them in terms of quality, design, engineering, functionality and performance.
    The earlier version Bosch headlights have 3 mounting tabs on top and no raised dots (nipples) on the front glass, later version Bosch have 2 mounting tabs on top and front glass raised dots that serve for aerodynamic reasons (better airflow at high speeds).
    They can be modified (as other brands can too) to HID but I think they are the best just how Bosch made them.
    See the later version Bosch E36 headlights with raised dots.

    you can put HIDS in anything with projectors. ZKWs, Bosch, Depos, etc. You can even do it to the US headlights. Once you go HID, you should change the projector as well, so the question of light output doesnt make sense. You can changing the bulb to HID and the projector, so the light output is much more dependent on the quality of those components, than the plastic housing that remains.

    theoretically break up the wind as it comes at the lenses to prevent whistling.
