Abstract:

A light emitting device for bicycles has a dynamo-like pinion arrangement. A spinner rotates an abrasive material across a flint, emitting sparks which illuminate a transparent or translucent vessel of the device. The device is mounted to one rear wheel strut of a bicycle frame and includes a mechanism which urges the spinner against the rear tire. A lock mechanism provides a second unengaged position for the device. A flint holder provides both a guide bore for the flint, and applies pressure behind the flint, thereby urging the flint against the abrasive material. This provides a non-electrical light source for bicycles in which sparks of intensity proportionate to the speed of cycling are created.
