LED bulbs used off-road or in auxiliary lights are legal everywhere. For on-road headlight use, legality varies by state.

Halogen bulbs produce a warm yellow light (around 3200K), last 500 to 1000 hours, and draw more power. LED bulbs emit a brighter white light (5000-6000K), last 25,000+ hours, and use less energy. LED upgrades for the HID-D2R LED position are available as direct plug-and-play replacements. Since the Mercedes-Benz uses CANbus monitoring, choose a CANbus-compatible LED kit to avoid dashboard errors.
