I’m looking to do a series of aesthetic mods to my vehicle, the first of which is adding integrated turn signal mirrors. I tried using a universal-fit turn signal (iJDMTOY 35-331) and K-Source glass; it looks okay, but the signal isn’t bright enough to be useful and the mirror’s heating element no longer seems to work, so I need to find another solution. I want to get a full assembly with the turn signal built-in, but the turn signal wasn’t available on the car, so such assemblies aren’t made.
Has anyone here ever done anything like this? Would it be possible to 3D-print a backing plate with a cutout for the turn signal, and cut “clearer” glass to shape?
