Should both headlights be replaced if one is damaged in a collision?

[VonCecilia]

If one headlight is damaged in a collision, only the damaged one needs to be replaced. Below is relevant information about automotive headlights: 1. Introduction to automotive headlights: Automotive headlights, also known as front headlamps or LED daytime running lights, serve as the "eyes" of a vehicle. They not only affect the owner's external image but are also crucial for safe driving at night or under adverse weather conditions. 2. Function of headlight adjustment: It allows the vehicle's lights to maintain appropriate height at all times, facilitating nighttime driving and adapting to different road undulations. 3. Importance of headlight adjustment: The more passengers in the rear seats, the lower the rear of the vehicle sinks, causing the front of the vehicle to rise accordingly. This raises the headlight height, potentially dazzling oncoming drivers and distracting their attention, which can easily lead to traffic accidents.
