I have an E30/M40 1989 318i (Euro Spec).
Iím working on a mod now, which is replacing the stock bulbs of the tail lights with custom (made by me) high power Led clusters. I was thinking instead of placing 8-9 LEDs in the space of the stock bulb, to place an entire cluster of LEDs that would occupy the whole tail light. What I mean by that, create a cluster of LEDs for the reverse lights, another one for the stop lights etc, but each cluster will have dimensions as long as the actual taillight part.
I have enough board, LEDs, time and solder with only a few concerns:
How many parts is the taillight assembly after removed? Can I remove the back cover so that the White, Yellow, Red plastic are totally exposed from the inside?
I want to know this because; if I canít remove the back (I donít want to cut it) cover, then the only room available for LEDs will be the small holes that are just as big as the stock bulb diameter.
If the cover along with the light reflector can be removed, then I will place the leds close to the red/yellow/white plastic, place the cover back, and then put the taillight back on the car.
If i can pull this off I believe that it would have no difference from buying the expensive taillight led assembly.
If everything works I'll post before/after pictures.
