Main Description
When your headlight leveling system is out of adjustment, you can experience dim or misdirected beams that annoy oncoming traffic and reduce nighttime visibility.

Built with a GRP (glass fibre reinforced plastic) housing, it is rugged enough to withstand engine bay temperatures and road debris while maintaining accurate sensing. The 4‑pin connector ensures a secure electrical connection, and the included holder, coupling rod, and frame help simplify installation and alignment. This is a genuine OEM-referenced replacement designed to restore original performance and comfort on affected VW models.
