Why does the headlight turn on when braking on a motorcycle?

The main cause of this malfunction lies in the brake light switch, which is divided into front and rear switches. Therefore, you can check the front brake light switch first, as in actual repairs, this issue is often caused by the front brake light switch. Simply unplug the connector on the front brake light switch temporarily, and the vehicle's brake light will turn off. If this is the case, purchasing and replacing the front brake light switch will resolve the issue, and users can easily perform this operation themselves. However, if the issue is not caused by the front brake switch, then the rear brake switch might be adjusted too tightly, with too small of a return gap. In this case, readjusting the gap can also eliminate the fault.
