Blue lights are against the law in California also. None of my lights were visible only a reflection.
A lot of you guys have rode with me all over the US and Canada with lights blazin......never was even an issue when I'd get stopped for speeding. That is until I put the blue Dakota Digital gauges in (now those are blue lights showing to the rear). It was a Sacramento City PD officer that pulled up next to me at a stop light and told me they were illegal but he never pulled me over and we went our own ways when the light turned green.
I've rode around a lot of LEO over the years and even I was surprised that they at least didn't use it for an excuse just to stop me.
Haven't had them since I sold me 10 SESG.
Besides, they'd be orange now.
