I live in WA but most of my boating is on the OR side of the river. Yeah, around here it's gonna depend on the situation and the personality of the authority. I've had MANY times in Oregon where I'm running or anchored with TONS of blue LED's glowing from everywhere on my boat and no worries whatsoever. They're really used to wake boats having blue LED's. I never ever make mine flash.

Brett, what you'd want for the future is something I'd honestly thought about and that's RGB-W. It's alternating RGB and white LED's and you can get a controller that will turn off the colors and turn on the white. and you can get cool combos like Red/white alternating and white/blue alternating. It increases it from 4 conductors to 5 and also requires a more expensive RGBW controller. But it'd be the bees knees for sure.
