Corner lamp.
A luminaire that provides auxiliary lighting near the road corner ahead of a vehicle or to the side or back of a vehicle. When the lighting conditions of the road environment are not sufficient, the corner light plays a certain role in auxiliary lighting and provides protection for driving safety. This kind of luminaire plays a certain role in auxiliary lighting, especially in areas where the lighting conditions of the road environment are insufficient.
Rear corner light failures can include bulb problems, faulty wiring, or broken taillights.
When the rear corner light (also known as the rear position light) fails, you should first check whether the bulb is normal. If the bulb is damaged, the light may not shine. In addition, if the bulb has been replaced before or related repairs have been made, the circuit connection may be affected, which can lead to failure. For example, after replacing the right rear brake light (i.e. rear position light), if the bulb is improperly installed or the type of bulb is not matched (such as using a one-legged bulb instead of a two-legged bulb), it may cause the light to not shine, even if the brake light will work properly .
Line failure is also a common cause of rear corner lamp failure. Wiring problems can include blown fuses, short circuits, or electrical leaks. These problems may cause the current to not pass through properly, which will affect the normal operation of the bulb. Checking the line connection and voltage is an effective way to diagnose line faults .
In addition to bulb and wiring problems, damage to the taillight itself can also cause failures. For example, a right taillight failure may be caused by a short circuit in the right rear reversing light or a damaged taillight . In this case, it is necessary to check the working status of the taillight and whether the relevant circuit connection is normal.
To sum up, the solution to the rear corner lamp failure needs to be investigated from the three aspects of the lamp, the line and the taillight itself. If self-inspection is difficult, it is recommended to seek professional maintenance services for inspection and repair.
There are two kinds of corner lights for cars.
One is a lamp that provides auxiliary lighting for the road corner near the front where the vehicle is about to turn, and is installed on both sides of the longitudinal symmetrical plane of the vehicle.
The other is a lamp that provides auxiliary lighting for the side or back of the vehicle when the vehicle is about to reverse or slow down, and is installed on the side, back or downward of the vehicle. This type of corner light is called a slow light.
The positive and negative terminals of the taillight
The positive and negative terminals of taillights are usually represented by red and black lines.
In the wiring of the car taillight, the red line represents the positive terminal, while the black line represents the negative terminal. This color coding is a common standard used to distinguish between positive and negative poles in a circuit. The red wire is usually used to connect the positive terminal of the power supply, while the black wire is used to connect the negative terminal or the lap wire of the power supply. This connection ensures the correct flow of current, so that the taillight can work properly.
The wiring of the taillight also includes other color lines, such as the yellow line connected to the left turn signal, the green line connected to the right turn signal, and the blue line connected to the small light. The way these lines are connected varies depending on the specific configuration and design of the vehicle, but the purpose of the red and black lines is the same, representing the positive and negative poles respectively.
During the wiring process, it is necessary to pay attention to the rear end of the wire harness wires cannot be short-circuited, especially between the cable and the lap wire. In addition, in order to ensure the normal operation of the taillight, it is necessary to ensure that the current can correctly flow from the positive terminal of the power supply through the taillight, and then return to the power supply through the negative terminal to form a complete circuit.
In general, understanding the wiring of the positive and negative terminals of the taillight is essential to ensure the normal operation of the vehicle's electrical system. By following standard color coding rules, wiring errors can be avoided, thus ensuring driving safety.
