I have a Cygolite metro on front flashing and a Cygolite Hotshot on rear. Both on steady flash. Front light very bright and easy to see even at a distance. I see it reflecting on traffic signs 100 yards out. Irritating? Maybe but I want to be seen. The motorists are already irritated that we are even out there. The rear is a bit directional and I believe more attention getting at a bit of a distance rather than close up, so that it spreads a bit.

Note; This is daylight riding, I don't generally ride at night. But on rare occasion right at dawn or dusk and I run the front on continuous at those times.
