Flashing or blinking lights on a bicycle use their own power source to generate lights, and their flashing action draws a motorist's eye toward a cyclist. Being visible to motorists is an important aspect of bicycling safety when riding at night, particularly when road cycling.
Since vehicles generally come upon a cyclist from the rear, most flashing lights are mounted on the back of the bicycle.
Flashing lights generally attach to the bicycle's seat post, although some lights can be mounted on the back of a rider's helmet, bag or apparel.
Flashing lights are mostly red in color, which is generally thought of as a universal "warning" sign color on the road.
Flashing bike lights generally use LED bulbs, which are known for their brightness and energy efficiency.
Most blinking bike lights run on two to three double "A" or triple "A" batteries and can run for up to and over 100 hours in flash mode.
