Why do the high beams turn on when using the turn signal?

It could be due to a short circuit in the wiring or an issue with the combination switch. Turn signal structure and principle: Resistive types can be further divided into thermal wire type (electrothermal) and flap type (spring-loaded). Electronic types can be categorized into hybrid (relay with contacts and electronic components) and fully electronic (no relay). For example, the spring-loaded flasher utilizes the principle of current thermal effect, using thermal expansion and contraction as the driving force to cause sudden movement of the spring plate, thereby connecting and disconnecting the contacts to achieve light flashing. Hazards of high beams: The probability of traffic accidents at night is 1.5 times higher than during the day, with 60% of major traffic fatalities occurring at night. 30-40% of nighttime accidents are caused by the misuse of high beams. When human eyes are exposed to the strong light of car headlights, the pupils automatically contract from the normal 5~8 mm to 1 mm or even smaller, reducing the amount of light entering to less than 1/30 of the original. After passing another vehicle, since the pupils cannot recover in time, the amount of light entering suddenly decreases, resulting in a phenomenon similar to night blindness, leading to numerous traffic accidents.
