LED Dynamic Turn Signal Lights for Mercedes-Benz W204 S204 W164 Vito Viano
Upgrade your Mercedes exterior lighting with these LED dynamic turn signal lights, precision-engineered for the C-Class W204/S204, ML-Class W164, and Vito/Viano W639 facelift models. Featuring a sequential scroll flasher design, the indicator flows outward across the smoked ABS housing before triggering the full turn cycle. The 2400LM output significantly improves roadside visibility compared to dim stock halogen bulbs, while the direct T10 interface connects straight to your factory wiring harness without triggering error codes or requiring additional programming. This straightforward plug-and-play solution replaces aging reflector units, reduces blind-spot hazards, and integrates a streamlined OEM appearance directly onto your side mirrors.
Benefits & Tips
- Perform the swap after the ignition has been switched off for at least ten minutes to allow the mirror mechanisms to fully retract and cool.
- Preserve lumen output by cleaning the smoked polycarbonate lenses monthly with a damp microfiber cloth; avoid abrasive solvents that can cloud the housing.
- A momentary flicker during initial cold starts is normal CANbus verification and will stabilize immediately once the unit completes its power-draw handshake.

Warnings & Reminders
Because these units mount directly to the exterior mirror casing, professional installation is highly recommended. Detailed step-by-step instructions are not included. Please account for up to 2 mm dimensional variance due to manual molding processes, and note that housing tint may appear slightly deeper under different lighting conditions than shown on-screen.
