The function of the bright strip on the front bumper of the car
The decorative strip on the front bumper of a car usually refers to the decorative strip-like accessory installed on the front bumper of the vehicle. Its functions mainly lie in both the decorative aspect and the functional aspect.
Enhancing visual appearance: As an important exterior decorative component, the front bumper strip can significantly enhance the fashion, dynamic, and luxurious feel of the vehicle. It achieves this by being treated with mirror chrome or bright silver finish, forming soft highlights under sunlight, which enhances the horizontal visual extension of the vehicle body, making the front end more layered and recognizable, thereby improving the overall appearance of the vehicle.
Protecting the vehicle and pedestrians: In the event of minor scratches or collisions, the strip can act as a buffer, reducing damage to the front bumper itself, providing protection. At the same time, its design also aligns with the concept of pedestrian protection, reducing harm to pedestrians in case of an accident.
Enhancing practicality: Some of the strips are made of high-strength materials (such as ABS + electroplating, 304 stainless steel), featuring anti-corrosion, high-temperature resistance, and resistance to fading and deformation, which can effectively cope with wear and tear from daily use such as washing and stone splashes, extending the lifespan of the front bumper.
In addition, the installation method of the front bumper strip is diverse. Some models use a buckle fixation (such as the Hongqi H5), which does not require drilling or gluing, making disassembly and assembly convenient; others use 3M double-sided adhesive for installation, and during installation, it is necessary to ensure the surface is clean to ensure a firm bond.
The failure of the front bumper strip may involve two main situations: one is the physical damage or aging of the decorative chrome strip, and the other is the activation of warning lights in the vehicle's front bumper area (such as fog lights, fault indicators). The nature of these two situations is different, and they need to be handled separately.
Failure of the decorative chrome strip on the front bumper
If "the front bumper strip" refers to the chrome decorative strip on the bumper, its common failures include deformation, detachment, rusting, or scratches, which do not affect the vehicle's performance but do affect appearance.
Repair methods:
Minor scratches or fading: You can try using specialized metal cleaners (such as copper-removing paste, WD-40 universal anti-rust agent) or carburetor cleaning agents (note to avoid contact with the car paint) for cleaning and polishing to restore the luster.
Rust: Toilet cleaner or specialized rust removers can effectively remove the rust under the chrome layer, but thorough rinsing and drying are necessary to prevent residual corrosion.
Detachment or loosening: If it is only due to aging of the adhesive causing detachment, you can clean the backside and reattach it using automotive strong adhesive.
Severe deformation or fracture: Such damage cannot be repaired and must be replaced with a new part.
Replacement suggestions:
The front bumper strip can be replaced separately without replacing the entire bumper. The price ranges from several hundred yuan to several thousand yuan, and the price of original factory parts is higher.
When replacing, pay attention to the position of the buckle. For some models, it can be disassembled and assembled by yourself, but it is recommended to have a professional operator perform the operation to avoid damaging the bumper.
Long-term exposure to sunlight, high temperatures, or bumps are the main causes. It is recommended to park in a shady area to avoid direct sunlight.
Failure of the warning lights on the front bumper
If "the front bumper strip" refers to the fault indicators in the vehicle's front bumper area (such as the front bumper lights of models like Lincoln Navigator), this is usually a warning issued by the vehicle's electronic system and requires high attention.
Possible causes:
Fog light failure: Bulb damage, aging of the wiring, or poor contact.
Sensor failure: Abnormalities in oxygen sensors, air flow sensors, water temperature sensors, etc., causing the engine management system to report an error.
Fuel system problems: Poor-quality gasoline, pump failure, or poor fuel supply, affecting combustion efficiency.
Electrical interference: Installation of additional equipment (such as locators) interfering with the original vehicle wiring, or damage to the internal light-emitting components of the vehicle logo.
System misreporting: Temporary misjudgment by the computer system, which can be cleared by power-off reset.
Processing steps: Try to reset by cutting off the power: After turning off the engine, disconnect the negative terminal of the battery, wait for 30 seconds, then reconnect it. Start the vehicle and observe if the lights go out.
If the lights are still on but the vehicle is running normally: It is recommended to go to a 4S store or a professional repair center as soon as possible, use a fault diagnosis tool to read the fault codes, and accurately locate the problem.
If the lights are on and accompanied by power loss, inability to start, etc.: Immediately stop driving and call for help to avoid damaging the engine.
Summary:
If it is a decorative strip damage, it can be repaired or replaced depending on the situation. Prioritize cost and aesthetics.
If the warning light is on, it is a vehicle fault. It must be diagnosed in time to ensure driving safety.
