The popularity of LED car lights aftermarket remains high, and many owners of original halogen lamps hope to replace LED light sources to improve nighttime lighting effects. However, a large number of low-priced LED light bead products on the market lack matching optical lenses, causing severe glare after modification and interfering with other road participants. Traffic management departments in many places continue to carry out science popularization, clarify the compliance requirements for LED light modification, and remind car owners to choose lighting upgrade solutions rationally.

Many car owners have seen merchants promoting on short video platforms that simply replacing the light bulb without changing the original car circuit can significantly improve the brightness of the headlights. This type of product is inexpensive, easy to install, and attracts a large number of car owners to try it out. But the headlight engineer explained that the reflector bowl of the original car's halogen lamp was designed according to the emission position and angle of the halogen light source. Directly replacing the LED beads, the position of the light emitting point is not consistent with the halogen bulb, and the light cannot be collected by the reflective bowl. The light scatters upwards and there is no standardized cut-off line for brightness and darkness. Although the car owner feels that their field of vision has become brighter, the oncoming driver will experience strong glare, which can easily lead to brief visual blind spots when passing at night, posing a safety hazard.

The annual inspection of motor vehicles is not just about testing the brightness of the lights, but also requires that the model, color, illumination angle, and light distribution structure of the lamps comply with national standards. Replacing high-power LED bulbs without authorization, even if they barely pass the inspection in the short term, still constitutes illegal modification when driving on the road. Once a traffic accident occurs, the issue of modifying LED lighting fixtures will affect the determination of accident liability and insurance claims. Installing external LED spotlights or modifying colored LED taillights without authorization, in addition to the front headlights, is also considered a violation. The national standard specifies that external lighting signal lamps for vehicles can only use specified light colors such as white, amber, and red, and cannot add colored lights arbitrarily.

Compliant upgrade of LED headlights, priority should be given to LED headlight assemblies with complete lenses. The entire set of lighting fixtures has undergone vehicle standard testing, and optical distribution, heat dissipation, and waterproofing all comply with national standards. They are installed by professional stores and calibrated for lighting height and left and right angles. If the original car lampshade ages and turns yellow, it will reduce the efficiency of LED lighting utilization. Before upgrading the lighting, you can first renovate the lampshade, clean the stains inside the lampshade, and improve the lighting effect.

There is a significant gap in the quality of LED modified products in the market. Qualified automotive grade LED beads with a complete heat dissipation structure, slow light decay during long-term operation; The cooling design of low-priced products is simple, and after being lit for a long time, the temperature rapidly increases, the brightness of the lamp beads rapidly decreases, and in severe cases, the circuit may overheat, posing a hidden danger to the circuit. Many low-priced products have not undergone high and low temperature, waterproof testing, and are prone to fogging of the lamp chamber and circuit failures in rainy seasons and environments with large temperature differences.

The traffic management department reminds that road lighting requires joint maintenance by all traffic participants. Upgrading car lights should not only consider one's own field of vision, but also take into account the safety of other drivers and pedestrians on the road. If the original car lights decay, priority should be given to investigating basic issues such as aging lampshades and poor circuit connections. Do not blindly pursue ultra-high brightness LED light sources. The car lighting industry association is also promoting the standardization of the aftermarket, promoting compliant LED assembly products, guiding modification stores to standardize construction, reducing the flow of non compliant LED lighting products into the road surface, and maintaining nighttime road traffic order.
