How to Replace an RV Tail Light: A Step-by-Step Guide

If you've ever faced a situation where your RV's tail light has stopped working or suffered damage, you’re not alone. Tail lights are essential not only for aesthetics but also as a legal requirement for safety on the road. Fortunately, replacing a tail light is a straightforward task you can handle yourself. With guidance from our experts, Matt and Bart, you’ll be equipped to tackle this repair in no time.

Step-by-Step Instructions for Replacing an RV Tail Light

Step 1: Gather Your Tools

Before you start, make sure you have all the necessary tools ready. Here’s what you’ll need:

• Screw gun with a #2 square bit
• Wire strippers
• Bell caps
• Electrical tape
• Shop rags
• Isopropyl alcohol
• Adhesive remover
• Razor knife
• Putty tape
• Caulk gun and sealant
• Rubber gloves

Having these tools at your fingertips will streamline the process and make the replacement smoother.

Step 2: Disconnect the Power

Safety is paramount. Disconnect the 7-way connector from your tow vehicle to eliminate any 12-volt power supply before you begin working on the tail light.

Step 3: Remove the Lens and Base

To access the tail light, remove the lens cover. Remember, the tail light also serves as a license plate light, so keep this in mind when ordering a replacement part. After removing the lens, unscrew the base of the light and gently score the sealant around the perimeter to separate it from the rear wall.

Step 4: Expose Electrical Connections

Once the base is removed, access the electrical connections. Carefully pull the attached wire from inside the wall and cut it. Clean the area on the rear wall, removing any old putty and sealant to prepare for the new installation.

Step 5: Prep the New Light

Apply butyl or putty tape to the back of the new tail light. Strip back about half an inch of insulation from both the coach wires and the new light. Use bell caps to secure the connections in the same orientation as they were removed.

Step 6: Test the Lights

Before finalizing the installation, reconnect the 7-way connector to the tow vehicle and test the new tail light for functionality. Ensure everything is working correctly before proceeding.

Step 7: Reattach and Seal

Secure the new tail light to the rear wall by screwing it in place. Reinstall the lens cover and seal the perimeter of the light to prevent moisture intrusion.
