Sure....it's illegal but......
If you do it tastefully, you can get away with it, and most cops wont even know. Back in 95, I tinted the taillights of my other car (93 Hyundai Excel) I used Nightshades tint spray, and sprayed it in the inside of my taillight housing and let it swish around until it was partially dry, then i set it sit in the sun and dry the rest of the way. I've seen people spray the outside of their lights, and it looks like crap, no matter how good they spray it on. I lived in Va for about 4 years, and have been puled over by dozens of redneck cops (no offense to anyone) and they have never said anything about my lights, just wrote me up for other crap. Give it a shot. Good luck.
