LED vs. Halogen Upgrade Considerations

Upgrading your 2025 Metris to LED bulbs can significantly improve visibility and give your van a more modern look. However, there are a few things to keep in mind:

• CANBUS Errors: Mercedes-Benz vehicles use a CANBUS system to monitor the vehicle's electrical components. Since LED bulbs draw less power than halogen bulbs, the system may think a bulb is burnt out and trigger a "bulb out" warning on your dashboard. To prevent this, you'll need to purchase "CANBUS-ready" LED bulbs or install an in-line resistor for each bulb.
• Adapters and Fitment: While most LED replacement bulbs are designed to be plug-and-play, some locations, particularly the low-beam headlights, may require a special adapter to hold the LED bulb securely in the housing. Always check if an adapter is needed for your specific application.

How to Replace Each Bulb

• Headlights: Access to the headlight bulbs is typically through the back of the headlight assembly, which can be reached from under the hood. You may need to remove a dust cover to access the bulbs.
• Fog Lights: Fog light bulbs are usually accessed from underneath the front bumper or by removing a small panel in the wheel well.
• Tail Lights and Rear Bulbs: To replace the tail light, brake light, or turn signal bulbs, you will likely need to remove the tail light assembly from the outside of the vehicle. Look for screws on the side of the assembly in the door jamb area.
• License Plate Lights: These small bulbs are housed in a small assembly above the license plate. You can usually pry the lens off with a small flathead screwdriver to access the bulb.
• Interior Dome/Map Lights: Use a plastic trim removal tool to gently pry off the lens cover to avoid scratching the plastic. The bulbs can then be easily swapped out.

Common Lighting Issues for this Generation

As this is a new model, long-term common issues have yet to be identified. However, based on other Mercedes-Benz models, premature burnout of halogen bulbs and CANBUS errors after aftermarket LED installation are potential issues to be aware of.
