You can get bulb paint/tint, I used it on my first car years ago. I did mine blue and the police didn't like it because it's classed as impersonating them over here in the uk.
I had blue strobes aswell and would have them on and flash the headlights at night, the amount of people who pulled over and you'd just drive past and laugh at they're pissed faces!!
Oh to be young!!lol
