Need some help from the sifus here.I just got my E34 recently, and I noticed the headlights are not too bright, esp the passenger side that dont project over my boot (view from my side).Last weekend, I dismantled to clean the low beam headlights to clean the units, dust and all. The head,ights were much brighter after removing the dust from the lens and reflector units.my problem: I noticed that my left unit reflector (topside) have faded. And both reflector have cracks (like overheated) near the bulb area. This was what affected my left headlights.Is it possible to just change the reflector units, and not the whole headlights set?? Can anyone recommend any shops (potong or others)??Also, is there a way to "re-coat" the reflector units if i can find potong ones??Pls help, all feedback is appreciate
