Please ensure your correct model is selected

Cracked, pittted, sandblasted, hazed, and fogged headlight lenses can be a dangerous liability. They drastically cut light output than even the best bulbs will not overcome. There are headlight restoration kits on the market but even polishing and filling will not last much longer than a couple of weeks. Don't prolong their replacement! Only a new set of lenses or housings will restore your lighting's performance. And installing new headlight assemblies is generally straightforward and easy on most cars. Note that some BMW headlight lenses are sealed to the housing with silicone and the only replacement lens comes with a new housing.

Over time, road grime, salt, and moisture take a toll on the factory rear leveling rod. The original equipment often corrodes, seizes, and eventually snaps—or worse, binds up and breaks your expensive headlight leveling sensor. With this issue in mind, ECS has engineered a heavy-duty, bulletproof solution designed to outlast the car it’s installed on.

Instead of brittle OE plastic that degrades and snaps over time, this rod is constructed from high-strength, flexible polyurethane. Paired with corrosion-resistant stainless steel ball studs, it guarantees smooth articulation and prevents the binding that destroys expensive sensors. Precision-manufactured for a perfect, bolt-on fit, this upgrade requires zero modifications to replace your fragile OEM unit.

This is a direct-fit replacement for Genuine BMW part number 37146752797, restoring proper suspension-to-sensor geometry so your headlights adjust perfectly to changing loads and road conditions.
