John.....you might wanna check with local law enforcement on their legality. I used to have a license plate light from Custom Dynamics (the knight riderz light) mounted on my bike. This one.....
I asked several leo's about it (sheriffs, local law, military police (I work on an AF base)) and all of them told me the same thing.......the brake modulating was OK, but the flashing/back and forth light was technically illegal.......HOWEVER......they ALL said the same thing about it......no leo would mess with me about it by itself as they all understand that I'm trying to be more visable, but if they were to catch me doing something stupid, then I'd get a ticket for it.
I took it off last winter. No sense in fanning the flames in case I do get pulled over for doing something stupid.
