I believe I read a comment in a thread here that in many states a flashing red rear light may be illegal.

Does anyone know what the status of that is in Illinois?

Also, is it the general consensus that a solid light is better than flashing? I read that it helps to gauge distance, but I would think flashing would be a better attention getter.

Most of my commute is on low traffic routes or bike path (at least until winter), but if I keep it up through winter I will have to be on busier roads and want to know what would be safest.

Thanks!
