Im blind as a bat but managed to see the ones on IcarusGreen's (forgot your real name) clear as day infact the first few times he hit the brakes the quick flashes made me jump! If I can see them then that sells them to me lol
I've been in France on it since thurs, blue skies, 28deg the whole way, 2 bikes I'm with said its clear as day re brightness. The 24hr is the nuts btw.
