What is a car rear turn signal
The rear turn signal of a car, also known as the rear turn signal , is installed at the rear of a vehicle and is used to alert drivers of vehicles behind to the direction of their turn when making a turn.
Functions and Features
Youdaoplaceholder0 color : generally yellow light source
The function of is : by flashing the lights, it informs the driver behind the vehicle of the vehicle 's intention to turn, reducing the risk of collision
Youdaoplaceholder0 distribution : symmetrically distributed left and right, flashing synchronously with the direction of the steering wheel rotation
For some models, the rear turn signals may be integrated into the rear combination lights, together with the brake lights, reverse lights, etc., to form the rear lighting system.
The main function of the rear turn signal (also known as the rear turn signal) of a car is to indicate to other traffic participants the direction in which the vehicle is about to turn, and at the same time, it conveys specific warning signals in different scenarios:
Steering indication
By flashing or continuously lighting up, it clearly informs the drivers of surrounding vehicles of the vehicle's driving direction (left/right), helping other traffic participants predict the vehicle's movement in advance and avoid the risk of collision caused by lane changes or turns.
Emergency Warning
When the rear turn signals on both sides flash simultaneously, it may indicate that the vehicle is in an emergency state (such as a malfunction or the need for assistance), alerting other vehicles to avoid or slow down.
The color and function of the lights are distinguished
Youdaoplaceholder0 red brake light : It is used to warn vehicles behind to slow down or stop, and is usually installed in the center of the rear of the vehicle.
Youdaoplaceholder0 yellow/red rear turn signals : located on both sides of the rear of the vehicle, they flash to alert other vehicles to give way.
Faults of car rear turn signals (usually referring to taillights or turn signals) can be caused by various reasons, commonly including damaged bulbs, poor circuit contact or abnormal control modules, etc. The following are the specific troubleshooting steps and solutions:
The bulb is damaged.
The most common reason for the turn signal or taillight not working is that the bulb is burned out. For instance, if the right front turn signal of a Lavida model does not light up, it is necessary to check whether the filament is broken and replace it with a bulb of the matching model to solve the problem.
Poor circuit contact
Long-term use may lead to oxidation, loosening or corrosion of the circuit joints, especially when the turn signals or brake lights are frequently used. It is necessary to check the contact condition between the plug and the socket. Clean or replace the interface if necessary.
The fuse has blown
Some models (such as the Volkswagen Golf) may experience blown fuses or poor contact. It is necessary to check the fuse plate corresponding to the circuit in the fuse box of the engine compartment. If a fuse is found to be blown, a thicker pin fuse or the fuse box should be replaced.
Flash relay failure
Abnormal flashing of turn signals (such as rapid flashing) may be caused by damaged relays or aging components. It is necessary to check whether the relay is abnormal. If necessary, replace it with a matching model of flash relay.
Special function Settings
Some car models (such as Volkswagen and Mercedes-Benz) may have delayed functions like "Accompany Me Home". It is normal for the car lights to go out for a delay after locking the car. You can reset them by operating the car door again.
Youdaoplaceholder0 Emergency response : If you are unable to check it yourself, you can temporarily disconnect the fuse plate corresponding to the headlight in the fuse box (take a photo to record the position) to prevent the battery from draining power.
The damage to the rear taillights of a car needs to be handled according to the specific situation:
Selection of maintenance plan
If the damage is not severe, you can try simple repairs or replace the lampshade. If the lamp body is severely cracked, the entire set needs to be replaced. It is recommended to give priority to choosing 4S stores for maintenance to ensure the quality of original factory parts, but it is necessary to weigh the maintenance costs against the increase in insurance premiums.
Troubleshooting
The rapid flashing of turn signals may be caused by damaged bulbs, poor circuit contact or faults in the flash relay. It is recommended to check the status of the bulbs, circuits and relays.
