this topic is right up my alley, i have blue leds as my turn signals. I got stopped for them, and it was rather funny. the cop asked me if i knew they were illegal, and acting like a dumbass i said i had no idea. So he's like, i'll let ya go on this one and a bit of advice, just dont use your blinkers, its not a law in this state(south dakota). haha, thought it was pretty funny coming from an officer.
