Abstract

Abstract A device for use with a motorcycle helment is disclosed which directs a safety light rearward from the lower back portion of the helmet. The light is removably mounted onto the helmet with a variety of mounting apparatus, each of which allows the light to be quickly and conveniently installed and removed from the helmet. The light, which is entirely self-contained, is mounted onto the helmet in a way allowing the light to detach itself during an accident to avoid inflicting serious head or neck injury on the rider due to the light becoming snagged during the accident.
