Are the headlights replaced at a 4S store genuine?

[KalebDella]

Headlights replaced at a 4S store are genuine. If unsure, you can compare them with the original headlights. Aftermarket headlights generally have poorer illumination effects, longer response times, and may even exhibit uneven brightness between the left and right sides. The quality of aftermarket headlights varies, and there are often many flaws in the edge connections of the headlights. Below are some headlight maintenance methods: 1. Regularly clean the lamp covers. While driving on the road, water splashes can cause mud spots to accumulate on the headlight covers. Generally, headlight covers are made of special materials with good sealing. However, scattered mud spots on the covers not only affect the car's appearance but also impair the headlights' illumination. 2. Routinely check if the headlights are functioning properly. When inspecting the headlights, ensure that all types of lights (such as turn signals, tail lights, fog lights, etc.) are working correctly. Additionally, check if the direction of the headlight beams has shifted and if the brightness is sufficient. Regular checks on the headlights' condition can help you stay informed and prevent unexpected issues.
