、ペダルの回転が重くなり走行性が悪いという欠点があ
る。(b) Prior Art Conventional bicycle headlight lighting devices are generally one that uses the electromotive force of a generator that generates electricity as the wheel rotates, and one that uses dry batteries. However, the method (■) has safety problems because the lights go off when the vehicle is stopped or when driving at low speeds. For this reason, some proposals have been made to install a secondary battery and charge it with a generator, and then turn on the battery using the discharge current of the secondary battery when the vehicle is stopped or driving at low speeds, but this increases the load on the generator and the pedal The disadvantage is that the rotation becomes heavy and running performance is poor.

等の欠点がある。In addition, method (■) does not have the drawbacks of method (2), such as not being able to turn on the headlights and making the pedals heavier when stopped temporarily or when driving at low speeds, but the battery capacity is limited because bicycles have little battery storage space. This is not only uneconomical as it requires frequent battery replacement, but if you forget to replace the battery, you will be forced to drive without lights, which is dangerous.Furthermore, if you forget to turn off the battery, it is a waste of battery power. There are disadvantages such as high consumption.

A switching means is interposed between the headlamp and the secondary battery, detects running and stopping of running based on the output of the generator, and turns the switching means ON/OFF during running.
The above problem is solved by providing a control circuit that turns off with a delay after the vehicle stops running.
