Upgrade your Mercedes-Benz visibility with these LED dynamic turn signal rearview mirror lamps. Designed as a direct replacement for OEM part numbers 2048200721 and 2048200821, this one-pair set upgrades your W204 C-Class or W639 Vito/VIANO with a modern amber scanning pattern. The semi-smoked black lenses reduce driver glare while the integrated 12-volt LED modules deliver a focused 2400-lumen output that cuts through fog or flat daylight. Engineered for straightforward maintenance, the assemblies connect directly to your factory harness without triggering dashboard error codes or requiring ECU software adjustments.

Benefits & Practical Tips
Keep lane changes legally compliant and instantly noticeable to adjacent traffic. Verify your vehicle matches the 2007–2014 facelift styling before unpacking, as older pre-facelift VITO and C-CLASS brackets differ physically. Once mounted, recalibrate the side mirrors slightly downward so the continuous amber sweep projects exactly where other motorists anticipate directional signals. Wipe the tinted housing occasionally with a clean microfibre cloth to preserve the scratch-resistant matte finish against road salt and highway debris.
