I did just opposite. I left the reds normal, and tinted the amber. I plan on evening it out with either red/red tail lights, or tinting the amber part to match. I also took apart 98/99 style turn signals and blacked out the inner housings. And 1 very light thin layer of tint on the lens.
Here's a photo of the beast.
Now I dont understand the HIDs, and the Black out rears. It totally contradicts itself.
Is your kit the full out projector, ballast, etc? ...Or a plug and play bulb?
If you're going for merely asthetics, I suggest doing angel eyes like mine. They catch attention very well. And they dont blind drivers like unRetrofited HID's do (a video on youtube shows how bad HID's really are in reflector style housings)
Well hey! If you need a hand with Angel Eyes and housing blackouts, I'm a smart cookie, most times. Shoot me a msg!
If you're going into more projector HIDs, I struggle there, but ROACH (and another fellow member I contacted, forgot the name...) is a smart man there!
