願平5−270466号として出願している。2. Description of the Related Art Normally, a bicycle is equipped with a headlight that uses a dynamo as a power source, and when traveling at night, this headlight is lit to ensure the safety of running and to prevent accidents by notifying other vehicles of its existence. It is designed to work. However, driving the dynamo inevitably puts a load on the wheels of the bicycle and makes the pedals heavy, so there are many cases where the vehicle is driven without turning on the headlights, and accidents are easily encountered. Further, even if the headlight is turned on, it is difficult to check from the lateral direction and the rear side, and there are cases of accidents from the side and rear sides. Moreover, the dynamo produces a small amount of power when the bicycle is pulled and walks, and the headlight does not emit strong light. For the purpose of solving the above-mentioned problem, the present inventor attaches a light-emitting body to both sides and rear of a headlight, and makes the light-emitting body emit light by supplying power from a battery only when a bicycle is traveling at night. I have applied for a safety device as Japanese Patent Application No. 5-270466.

役立つ。The vibration detection sensor detects the vibration when the bicycle is running or when the bicycle is pulled down from the bicycle and walks, and closes the power supply circuit, and opens the power supply circuit when the vibration is no longer detected. The day / night detection sensor detects the sunset (darkness of the surroundings) to close the power supply circuit, and detects the dawn (brightness of the surroundings) to open the power supply circuit. The light emitter emits light using a solar battery or other rechargeable battery as a power source. The battery is first charged with the power generated by the solar, and further charged with the power generated by the generator for the headlight, so that the problem of power shortage due to the solar does not occur. .
The light emitter automatically emits light when a bicycle is running or pulled at night and vibration occurs. When the front side of the headlight emits light, even if the user forgets to put on the headlight, the front side of the bicycle emits light, which helps prevent accidents.
