I used niteshades spray on tint.
If you don’t over do it, like window tint, It can make a car look alot better with out being dangerous. It dosent seem to make the slightest diffrence when my lights are on. So it looks better W/O obscuring anything.
I used 3 coatings, others I know have put on 8-9 and it is almost as dim as the when people use the abs plastic covers.
I’ve had it on my car for 2 years now and have never been bothered by the police for it. Even when I was pulled over for having a tinted cover over the licence plate. Or when I was pulled over for having my stereo “too loud” on 28, or well the point is cops never bothered me for the tinted lights, even after they have me pulled over.
