If a car headlight cover is cracked, it cannot be replaced individually; the entire headlight assembly must be replaced. This is because standalone headlight covers are not available for replacement, and only the full assembly can be installed. Some vehicle models do not allow direct replacement and require the entire headlight assembly to be removed. For models with compact engine compartments, this process may take more time and effort, requiring specialized tools and certain technical skills. Below is relevant information: 1. Reason for full replacement: The headlight assembly contains multiple components, and if one part is damaged and not repaired in time, it may eventually lead to the failure of the entire assembly. However, since replacing the assembly is considered a headlight modification, and annual vehicle inspections have strict requirements regarding headlight modifications (unauthorized modifications are prohibited), many people worry that replacing the headlight assembly may cause their vehicle to fail the inspection. 2. Car headlight assembly: Generally, as long as the replacement headlight assembly is an original factory part and identical to the original, it will pass the annual inspection. If the inspection reveals that the headlight brightness does not meet requirements, proper adjustment can ensure approval. However, modifications such as angel-eye headlights will not pass the inspection. Additionally, installing standalone LED or xenon lights without lenses will also fail the inspection.
