I have succesfully taken a set of the projectors apart and put them back together again. I bought the black housing ones from ebay and didn't care for the black housings on my wife's silver GP so I took them apart and color matched the housings to the silver of the car. I will be changing the color of the halos soon and no you don't have to take the headlight apart to change the halo color. The LEDs that illuminate the halos come out the bottom of the headlight (or at least on the ones I have they do). PICs to come soon!! Maybe I will do a write up on how to take them apart. I also made my halos and 3 LEDs in my headlights my DRL's. Think I should do a how-to on that too??
