[QUOTE 5038150, member: 9609"]I have only had one a week, did't realise there was so much opposition to them, the horse bit seemed a pretty obvious one to me hence why I covered it. However as a driver I think they are brilliant, you spot them in poor light at a considerable distance and know in an instant that its a cyclist.[/QUOTE]
I don't know why I don't like them, I just find them deeply unpleasant. I either turn off or just stop and wait if someone has a light brightly flashing near me. Less likely to bother me while driving, because headlights are typically brighter than even very bright bike lights, so the effected is muted.
Something to think about: could your lights trigger an epileptic fit in someone who was sensitive? That wouldn't be true of a little knog blinky, but a very bright light lighting up the surrounds then darkening then brightening again might.
Usual disclaimer: I don't know enough about photosensitive epilepsy to know for sure if a light is potentially dangerous. Just raising the possibility.
