First, check to make sure that the light bulb is not burnt out, or the main lamp holder is not burnt out. The probability of basic circuit problems and fuse failures is very small. Finally, if the lamp holder burns out, check the circuit. Car taillights don't work, usually because of poor contact or blown fuse, or because the light bulb is burnt out.

LED taillight is an innovative brake light and taillight, which has a long-term LED light source. When the car brakes, turns around or turns around, it can send a signal to other vehicles and pedestrians. LED taillights have excellent light source intensity and can maintain high visibility even in foggy days. In recent years, due to the needs of design, aerodynamics and aesthetics, low-side streamlined modeling has become more and more popular.

Compared with traditional lamps, light-emitting diodes have a series of technical advantages, among which short reaction time and long service life are the most important advantages. Seeing the brake lights of the car in front in time is helpful to reduce the parking distance of the driver. For example, when braking at the speed of 100 km/h under the same conditions, seeing the brake lights of the car in front in time can reduce the parking distance of the driver by about 5.5 meters.
