I own TnT Renegade Lights based in Texas, some states have certain color restrictions, but as long as they don't face forward or flash they are legal in the state of Texas. Some states such as Colorado don't allow green, because that is the color of the forest service. You need to check with the highway dept. in your state. I run my blue led's all the time, at night in Texas and haven't ever been pulled over for running them. We sell all colors of led lights and haven't had any reports of ticketing, as long as they aren't flashing.
