Why is the car brake light not on?

When the brake light is not on, it may be because the wick of the light bulb is burnt out, and a new light bulb needs to be replaced. If the new light bulb still does not light up, it is necessary to check the light circuit of the vehicle in time and troubleshoot in time to ensure driving safety. .

　　

The lights at the rear of the car are mainly used to remind the cars behind and convey their intentions to the cars behind. For example, when we step on the brake pedal, the brake lights will light up or become brighter to remind the cars behind that they are slowing down. Notice what it means to slow down. Or when encountering an emergency, step on the brake pedal deeply, and the brake light will be bright and flashing to remind the car behind that there is an emergency ahead and you need to slow down immediately to ensure your own safety. At the same time, in an emergency, the hazard warning lights can also be turned on at the same time, which will make it easier for cars behind to notice themselves. Therefore, the lamps and lanterns of the vehicle play a very important role in our driving safety and require frequent maintenance.
