1. These instructions cover removing an old taillight assembly and installing a new Mustang LED Taillight Assembly on a 1968 Mustang coupe.
2. Remove the original Mustang taillight assemblies by first removing the light socket/wiring, then removing the six taillight bezel nuts. The light socket can be removed by twisting it a half turn. Two threaded stems on each of the three bezels per assembly fasten the lens and taillight body in place and also get removed.



3. Once the taillight socket and six nuts are removed, pull the three bezels straight outward and the lens/body assembly will be free.

4. The next step is to disassemble the old lighting assembly.

5. To do this, first remove the rubber or foam taillight body pad.

6. Next, remove the six Phillip head screws that retain the lens.

7. Remove the old lens gasket.

8. I chose to clean and reuse my Mustang taillight bodies. The original taillight lens gaskets were replaced with Mustang Scott Drake taillight lens gaskets.

9. Rather than replacing the stock light sockets and bulbs with Mustang taillights that matched the originals, I decided to use Mustang LED style lights.


10. Pull the wiring connector through the back hole of the body and secure the LED fixture to the body/gasket assembly with six screws.

11. The original body pads were replaced with new Mustang taillight body pads. It is a good idea to fasten the bezel to the taillight assembly prior to fitting them on the car to ensure the holes in the body pads are correctly lined up with the holes in the light body.


12. The original taillight sockets can be reused. However, I am building new wiring harnesses from scratch, so I chose to buy Mustang taillight socket replacements. Install them by twisting them in the opposite way of how they came off.

13. Here is a rear view of the finished lighting assembly.

14. Here is a front view of the finished taillight assembly using a 12V DC test to show the brightness.

15. New Mustang taillight bezel pads were installed, using the existing bezels to secure the taillight assembly to the car.


16. If your Mustang taillight bezel nuts are all rusted, like mine, purchase and install new ones.

17. After fastening the bezels, connect the wiring to complete the installation of your Mustang LED Taillight Assembly.

Note: You will need a Mustang Two Terminal LED Flasher for correct operation of the blinker and hazard functions. The stock flasher relays are rated for lights with a higher electrical load. LED lights have a very small electrical load and need flasher relays appropriately suited.
