which brake light

The brake lights are located at both ends of the rear of the car, and the main color is red. The purpose is to enhance the penetration of the light source, so that the rear car can find the brake of the front car even in the case of low visibility, so as to prevent rear-end collisions.

　　

A car has headlights, fog lights, width indicator lights, turn signals, brake lights, reversing lights, license plate lights, and daytime running lights. Safe driving has a big impact. Headlights are divided into high beam and low beam. The high beam light source is high and far away. It is generally used on roads without street lights at night. When driving at high speed, it can also be used to prompt or overtake. It should be noted that when meeting cars, be sure to switch the high beam to low beam. The low beam light source is close and low, and is generally used on roads with street lights. The width indicator light is used to prompt the width and length of the vehicle body at night. The turn signal is used to remind vehicles or pedestrians to turn and merge, and the double flash in emergency is also realized by it. Brake lights are mainly used to tell the car behind to slow down or stop. Fog lights are used to help drivers improve visibility in foggy weather. The reversing lights will come on synchronously when the reverse gear is engaged. The license plate light is used to illuminate the license plate at night, and the Road Traffic Safety Law stipulates that the camera light must be turned on when driving at night. Daytime running lights are specially used to remind pedestrians or cars to pay attention to safety when driving during the day.
