I was into exterior light modifications but i kinda grew out of them i guess. I had 7 color underglow on my old car.
I think you mod is good in theory but you would ave to keep a few things in mind.
If you don't block off the light source then it will glow out of the "PONTIAC" and also shine on the ground. This will divert attention from where you want it. Also dim the lights.
Also make sure your light source is very bright, i have been disappointed by what i thought were going to be bright lights and turned out otherwise..
