It shouldn't need to be said over and over but people still don't get it. If you are not an emergency vehicle going to an emergency please use a solid light at the front. Ideally at the rear as well but most especially always at the front. It is extremely dangerous to ride with a flashing light at the front, it dazzles and blinds people and then they cannot see and as a cyclist not being able to see because some jack hole felt the need to flash to make himself have the illusion of more safety while hurting others is just not helpful. Cars don't have flashing lights, motorcycles and scooters don't have flashing lights. Why must we do it?
