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 H6054 bulb counter-clockwise to remove it, then insert the new bulb and reassemble. Note: Mercedes-Benz vehicles use a CANbus system, so LED replacements may need an anti-flicker decoder. The whole process typically takes 10 to 30 minutes per side depending on accessibility.

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

A pair of halogen H6054 bulbs costs $15 to $40, while LED conversion kits run $25 to $60 per pair. If you have a shop do the work, expect an additional $20 to $50 in labor per bulb. Replacing them yourself at home saves the labor cost and usually takes under 30 minutes.

What is the difference between halogen and LED for a 1985 Mercedes-Benz 190D?

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 H6054 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 1985 Mercedes-Benz 190D?

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 H6054 low beams, as they see the most use. Adding a matching 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.
