Judgment and troubleshooting of the fault (1) If the brake light on one side is on and the brake light on both sides is off, first check whether the brake light bulb of the non-bright side is open circuit, and whether the voltage on the black/red conductor at the lamp socket is normal. If all are good, check whether the ground wire contact is good and whether the lamp bulb is in good contact with the lamp holder.

Brake lamp does not work properly when operating the sweeper. Causes and Solutions
The sweeper, like the most vehicles, is equipped with a brake light at the rear. If the brake light fails, it will have a great impact on the sweeper and cause serious accidents. Therefore, it is very important to diagnose the causes of brake lamp damage and to solve it. The general brake lights (brake lights) are mounted on both sides of the rear of the vehicle. When the driver depresses the brake pedal, the brake light is on and emits red light. Remind the rear vehicle to pay attention and do not rear-end. The brake light goes out when the driver releases the brake pedal.
