What are the rear corner lights of a car
Automobile rear corner lights are not a standard term and may refer to the following two types of lamps with similar functions:
Rear position light (width indicator light
Installed at the rear of the vehicle, it is mainly used to mark the width of the vehicle body and its presence, with a red light source. When the brake pedal is pressed, it will automatically light up to remind the vehicles behind to keep a safe distance. Some large vehicles (such as buses and trucks) are equipped with multiple lamps on both sides of the rear to display the length and width of the vehicle body.
Reversing light
It is installed on the right side of the rear and uses a white light source. When the reverse gear is engaged, it automatically lights up to alert the vehicles behind to pay attention to the reversing action.
Both are located at the rear of the vehicle, but they have different functions: the rear position lights are mainly used for brake warning and body identification, while the reversing lights only light up when reversing.
The main functions of the car rear corner lights include:
Direction indication
The rear corner lights (usually red or yellow) are located in the rear corner of the vehicle and are used to indicate the vehicle's direction of travel to other drivers.
Auxiliary lighting
At night or in low visibility conditions, the rear corner lights can provide auxiliary lighting to the side and rear of the vehicle, helping the driver observe the road conditions.
Warning prompt
When reversing, the rear corner lights will illuminate to warn vehicles and pedestrians behind to be cautious and avoid them, reducing the risk of scratches.
Enhance security
By enhancing the visibility of vehicle contours, the probability of rear-end collisions is reduced.
The malfunction of the rear corner lights of a car may be caused by the following reasons:
Common causes
Youdaoplaceholder0 The bulb is broken
When one side of the rear corner lamp does not light up, first check whether the bulb on that side is burned out. For some models, the fuse may control the lights on one side alone. It is necessary to confirm whether the fuse at the corresponding position in the fuse box has blown.
Youdaoplaceholder0 line fault
If the bulb is functioning properly, it is necessary to check whether there is any open circuit or short circuit in the taillight circuit. Aging of the circuit, poor contact of the relay, and problems with the internal circuit of the fuse box can all cause faults. A multimeter should be used to test the voltage or resistance to identify the specific fault point.
Youdaoplaceholder0 the fuse blows
The new model may have a situation where one side of the fuse blows. You need to open the fuse box to check if the fuse with the corresponding number is blown. Replacing it with a fuse of the same specification can restore it.
Handling suggestions
Youdaoplaceholder0 Preliminary investigation : First, check if the bulb and fuse are abnormal. Pay attention to power-off safety during operation.
Youdaoplaceholder0 Professional inspection : If no problems are found after self-inspection, it is recommended to go to an auto repair shop to check for faults in the circuit or signal device to avoid potential safety hazards caused by aging lines.
The impact of replacing the rear corner lights (usually referring to reversing lights or taillights) of a car needs to be discussed on a case-by-case basis:
The impact on driving safety
Replacing the rear corner lights can enhance the lighting effect and reduce the risk of blind spots when reversing, but it is necessary to ensure that the bulb model matches and the brightness is moderate. Overly bright lights may interfere with others' vision and increase the risk of accidents.
The impact on vehicle value
Youdaoplaceholder0 Original factory specification replacement : If the taillights are replaced with the same parameters as the original factory and a reasonable reason (such as maintenance needs) can be provided, it usually will not significantly affect the value of the used car.
Youdaoplaceholder0 Non-original factory modification : Using non-original factory parts may cause the vehicle to depreciate, especially when it involves accident repairs, the overall repair cost may affect the assessed price.
Regulations and compliance
Privately modifying vehicle lights (such as changing halogen lamps to xenon lamps) may violate the "Road Traffic Safety Law", and it is necessary to have it operated by a professional institution to ensure compliance.
It is recommended to choose the type of bulb (LED or xenon lamp) based on actual needs and ensure that the operation is standardized to avoid safety hazards or legal risks caused by overly bright light.
