What is the difference between OEM headlights and aftermarket headlights?

[StAdriel]

The difference between OEM headlights and aftermarket headlights lies in their sealing performance: OEM headlight housings maintain their sealing performance without degradation, whereas aftermarket headlight housings may experience a decline in sealing performance over time. Headlights are a crucial component of a vehicle, serving the primary function of illumination. Without headlights, a car cannot operate safely at night. Additionally, headlights contribute to the vehicle's aesthetics, with some designs being particularly attractive. Headlights can be likened to the eyes of a car; well-designed headlights enhance the vehicle's overall appearance. If a headlight fails, it is advisable to replace it with an OEM headlight. Many vehicles use headlights manufactured by Valeo, known for their superior quality. Valeo supplies headlights to numerous automotive brands.
