I have some aftermarket lighting for different BMWs:
Brand new in box DEPOT LED half-clear tail lights, full LED brake and signal. Not cheap eBay junk but fade-resistant, condensation-resistant, plug-n play up grade for your E36 coupe to bring it into this century (cost approx.340 from DDM Tuning)
Brand new in box FULL interior "XENON blue" lighting kit for E39/E38. Obviously the kit is huge, 20 cool blue bulbs would work in other models as many bulbs are universal too but designed for E39/E38.
Nearly new 4200K HID bulbs D2S fitment x2
Brand new in box E36 Coupe 92-96 clear side markers from DDM Tuning, good quality will not fade/leak.
Might have an HID kit for sale with ballasts and 6000K E36 bulbs great for upgrade or for fogs...interested PM me for details.
