Preparation: Safety First

• Park your Mercedes on a level surface and engage the parking brake.

• Use a flashlight to inspect the surrounding area for any loose or broken parts.

Step-by-Step Guide: Changing Your Mercedes Tail Light

1. Remove the Tail Light Assembly:

• Locate the screws or clips holding the tail light assembly in place. These are typically located on the inside of the trunk or on the exterior of the car.
• Use your screwdriver or socket wrench to loosen and remove the screws or clips.
• Gently pull the tail light assembly away from the car. Be careful not to force it, as this could damage the surrounding components.

2. Disconnect the Electrical Connector:

• Locate the electrical connector attached to the tail light assembly. It will usually be located on the back of the assembly.
• Gently press down on the release tab on the connector and pull it away from the tail light assembly.

3. Install the New Tail Light Assembly:

• Connect the electrical connector to the new tail light assembly. Ensure it clicks securely into place.
• Align the new tail light assembly with the mounting points on the car.
• Secure the new tail light assembly with the screws or clips you removed earlier. Tighten them securely but avoid overtightening.

4. Test the New Tail Light:

• Turn on your car’s ignition and check all the tail light functions. Ensure the brake lights, turn signals, and reverse lights are working correctly.

Troubleshooting Common Issues

• If the new tail light assembly doesn’t light up: Double-check the electrical connector is securely connected.
• If the tail light assembly is loose: Ensure all screws or clips are properly tightened.
• If the tail light assembly doesn’t fit properly: Make sure you have purchased the correct assembly for your Mercedes model and year.

Tips for a Smooth Tail Light Replacement
