Except, of course, for officers Van Horn, Moreno, Tisdale, Hockney, etc. Come to think of it, I think theirs actually rotated...

The headlight modulator is legal in all states and Canada, but has to follow certain DOT/Canadian criteria. One is that it must not modulate after dark, there is a light sensor built in for that. I am not sure, but from reading up on it I think there is a California restriction on how many times the brakelight can flash before it stays steady. I'm sure I will be corrected if I am wrong on that.
