How to Install Tail Lights for 2005-2009 Mustang

1. Use a flat-head screwdriver to remove the 4 clips holding the plastic trunk trim in place.

2. Use an 11mm socket or wrench to remove the 3 nuts holding the tail light to the vehicle.

3. Remove the tail light housing from the vehicle and remove the bulb sockets by twisting them. Make sure to take note of each bulbs location so you can install them in the same order in the new housing.

4. Place the bulbs in the new housing. The location of the reverse light bulb will change slightly if you are installing the 2010 style tail lights (shown below).

5. Repeat Step 2-4 for the other side of the vehicle. Once the lights have been tested and work properly, re-install them onto the vehicle and replace any trunk trim that was removed to complete the installation.
