You would need to check your local lighting laws.

Every locale I've been in states that blue or red lights that are not in a factory position are for off-road use only. So like red lights that aren't tail lights, or blue lights that aren't head/fog lights are illegal if being used while on a public road.

Street Glow'* web site has a FAQ for local lighting laws though, so you should be able to find out there.

Basically you can have any light color you want on a car, however; the car cannot be operated on a pubic road or highway.

holy crap, can somebody sum that up bc thats a hell of alot of reading

It means if you dont have a permit, they can tow your car, suspend your license, and if they wish,.... rip the light kit out at the scene by whatever means necessary to ensure it isnt used in an illegal manner.

Like Purplehazeir said you can use them, but not while it'* being driven.

© No person shall drive or move any vehicle or equipment upon any
street or highway equipped with any device or lamp thereon capable of
or displaying a light of any other color than permitted by this section,

Notice I highlighted the key phrases here. And entire paragraph is Fed DOT (Notice the copyright symbol to the right) It comes right out of the Fed DOT Guidelines. It isnt state by state basis as some people and companies would allude it to be. There isnt a state body of government that can supercede Fed DOT law. And regardless what sites claim, you will find a disclosure statement on the packaging."Not for Street Use". You asked for a Legal Standing, thats it.

I am not here to say you shouldn't do it, I had top shelf, 4 LED sticks, 8 color, 86 pattern, strobing, etc. myself. Many inspection shops will deny you an inspection, and a few even call a Regional Inspector. And in every State if a Cop knows you have it, flashing or not, and has a hair up his azz, he can not only ticket you, he can physically remove it from your vehicle. That said I have seen cars rolling down the streets with them on, Lit up like a flashing Christmas Tree in parking lots, and I have seen cops ignore them. It'* your business, and your call, but at least know the real bottom line.

This is why I'm happy that Florida does not do inspections. I can do whatever I want to my car as long as it'* road safe.
