The exterior tail lights of the car do not have the function of creating a flowing effect.
The external taillights of the car do not have the flowing effect, which may be caused by various reasons, mainly divided into three aspects: vehicle design and configuration, system settings and faults, and modification possibilities.
Reasons related to vehicle design and configuration
Not all models have the flowing effect for their taillights. This is usually a trade-off made by the manufacturer based on overall design, cost control, and brand positioning.
Design trade-off: Some models (such as the Hongqi H9) have taillights that use light sources such as OLED, which have the potential to achieve the flowing effect. However, the manufacturer may not program the circuit and control system to ensure the stability and reliability of the vehicle.
Cost factor: Achieving a smooth flowing effect requires more complex circuits and control systems, which will increase production costs. Some models do not include this function to control the price.
Brand positioning: The manufacturer may consider that the existing lighting style (such as the continuous light band lighting from the middle to both sides) better represents its luxury and unique image rather than using the flowing effect.
Reasons related to system settings and faults
If your vehicle model is supposed to have the flowing effect for the taillights but does not display it, it may be due to the following issues:
Function not enabled: In the vehicle settings menu, there may be options such as "Lighting Effects" or "Welcome Mode", and it is necessary to confirm whether the flowing effect of the taillights has been enabled.
System failure: Faults in the lighting control system, sensors, or related control units may prevent the triggering of the flowing effect.
Electrical problems: Electrical issues such as blown fuses, short circuits or open circuits, unstable power supply, etc., will affect the normal operation of the lights.
Software problem: Temporary errors or configuration abnormalities in the vehicle control software may cause the function to fail.
Modification possibilities
If you want to add the flowing effect to the vehicle's taillights, there are the following ways:
Official software upgrade: Some manufacturers may add this function to existing models through subsequent OTA upgrades or 4S store software updates. Consult the official dealer.
Professional modification: You can consult a professional car modification shop to add the flowing effect by installing control modules or modifying the circuit. However, be aware of:
Risk warning: Self-modification may affect the original factory warranty of the vehicle and even pose safety risks.
Compliance: The modified lighting effect must comply with local traffic safety regulations to avoid penalties for excessive brightness, color, or dynamic effect.
Suggested operation steps:
Check the vehicle manual: Confirm whether your vehicle model is originally equipped with the flowing effect of taillights.
Check vehicle settings: Enter the central control system lighting settings to find relevant options and enable them.
Contact official after-sales service: If the settings are correct but the function is still missing, it is recommended to have a professional inspection at a 4S store.
Carefully consider modification: If you really need it, choose a reputable institution and keep the original factory parts for restoration. Software or control module issue: If a certain function was originally present but suddenly disappears, it might be that the software of the vehicle's lighting control module has temporarily malfunctioned, or the configuration of the related control program is abnormal.
Solution:
- Refer to the manual: First, confirm whether your vehicle model is officially supported for this function.
- Check the settings: Look for and enable the relevant lighting effect options in the vehicle's system or dashboard settings.
- Contact the 4S store: Consult the official dealer to inquire if this function can be activated through official software upgrade (OTA or in-store upgrade).
- Be cautious about modification: If the official does not support it, you can consult a professional modification shop, but be aware that privately modifying the circuitry may result in the loss of vehicle warranty and pose safety hazards.
Tail lights completely not working ("broken"): If your tail lights are completely not lighting up, this is a serious functional failure that affects driving safety and must be dealt with immediately.
Common causes:
- Bulb/LED module damage: The filament burns out after long use, or the LED light source is damaged due to aging or overvoltage.
- Fuse blown: When the circuit current is too high, the fuse will blow to protect the circuit. This is a relatively simple and common fault point.
- Circuit fault: Circuit aging, damage, short circuit, open circuit, or loose plug and poor contact.
- Control module failure: The switch, relay, or integrated control module responsible for controlling the tail lights is faulty.
- Troubleshooting suggestions:
- Check the bulb: Observe if the bulb is blackened or if the filament is broken.
- Check the fuse: Locate the fuse corresponding to the "tail lights" in the vehicle manual and check if it is blown.
- Check the wiring: Check if the tail light plug is loose and if the wiring has obvious damage.
- Professional repair: If the above steps cannot solve the problem, please immediately go to a professional automotive repair shop for diagnosis. The failure of tail lights is a major safety hazard, not only increasing the risk of being rear-ended but also violating traffic regulations.
- Summary: First, determine whether it is "lights not shining continuously" or "lights completely not working". The former may be a problem with the function settings or design, while the latter is a safety failure that must be repaired immediately.
