ABSTRACT:
A bicycle signalling device includes a housing, a reflective element for reflecting a light emitted thereto, a signalling lamp near the reflective element, a power source for supplying the lamp, a photosensitive element electrically connected between the signalling lamp and the power source for determining whether the lamp should be energized by the source in dependence upon an intensity of light, and a switch electrically connected between the power source and the signalling lamp for controlling an electrical conduction therebetween. Such device will enable the bicycle to be attention-calling at a dark night.
