Turn off the vehicle and open the hood. Locate the headlight assembly from behind, remove the dust cover or retaining clip, disconnect the wiring harness, twist the old 9004 bulb counter-clockwise to remove it, then insert the new bulb and reassemble.

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 9004 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.

Can You Put LED Bulbs in a 1996 Mercedes-Benz SL320?

Upgrading to LED is one of the most effective ways to modernize your Mercedes-Benz's appearance and safety profile. We recommend starting your upgrade with the 9004 low beams, as they see the most use. Adding a matching H1 LED kit later will complete the look and ensure consistent lighting performance. Because Mercedes-Benz utilizes a CANbus system, standard LED bulbs may cause "bulb out" errors on your dashboard. Always opt for "Error-Free" or CANbus-ready kits which include the necessary resistors. Don't forget the H1 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
