Context is important with lights, I think you'd have to be ignorant to run really bright lights on blink along a MUP. Slow down and keep the lights pointed downwards.
I think small blinkies aren't doing any harm, esp. as daytime running lights, as every car around here has DRL. I'm riding to work for night shift now, so while I have my lights on steady, the few cars I pass don't seem to give a rat's ass about my lights.
