1. Park your vehicle and turn off the engine.
Ensure the parking brake is engaged and the vehicle is in "Park" (for automatic transmissions) or first gear (for manual transmissions).
2. Locate the license plate lights.
The license plate lights are located on the rear of the vehicle, above the license plate.
3. Remove the old license plate lights.
Use a flat-head screwdriver or trim removal tool to carefully pry the lens cover off the housing of the license plate light. Once the lens cover is removed, you will see the bulb socket. Gently twist the bulb counterclockwise to remove it from the socket.
4. Install the new license plate lights.
Insert the new bulb into the socket and turn it clockwise until it is secure. Repeat this process for the other license plate light, if necessary.
5. Replace the lens covers.
Snap the lens covers back into place over the license plate lights.
6. Test the license plate lights.
Ensure the license plate lights are working properly by turning on the headlights and checking to see if the license plate is illuminated.
That's it! Replacing the license plate lights on a 2003 Chevrolet Avalanche is a simple and straightforward task that can be completed in a matter of minutes.
