Please call for details. I don't know if undercar neon is legal in my area. The best thing to do is go down to your local courthouse, or police station. And ask them about neon lights. They'll tell you everything you need to know to avoid trouble.
Most states have laws against certain colors, such as red and blue.
However, the patrolling officers usually tolerate other colors and you shouldn't receive any trouble. As with StreetGlow products, they pretty much interchangeable as far as linking methods go. You cannot install head light strobes in a sealed lens. It must be a composite only. No, StreetGlow accent tubes are not recommended to be installed outside the vehicle.
