Ford F150 2009-2014 Tail Lights
Installation Guide
Required Tools:
-
8mm Socket Wrench
-
Ratchet
-
Alcohol prep pad / Cleaner
Step 1: Remove Mounting Bolts
Open the tailgate to locate the two 8mm bolts securing the tail light on the inner edge. Use an 8mm socket wrench to remove them.
Step 2: Remove Factory Tail Light
Firmly grasp the tail light assembly and pull it straight back to release it from the vehicle's retaining clips.
Step 3: Remove Factory Bulbs
Twist the bulb sockets counter-clockwise to remove them from the housing. Pull the old halogen bulbs out of the sockets (Note: Keep the factory sockets as they are needed for the new lights).
Please reinstall the factory reverse bulb (bottom socket) into the new tail light housing. The LED connector only replaces the brake/turn signal bulb.
Step 4: Connect Wiring
Plug the connector from the new LED tail light into the factory bulb socket. Note: Ensure the black wire aligns with the ground (negative) for proper polarity.
Step 5:Mount Load Resistors
Clean the metal surface behind the tail light. Peel the backing off the load resistor (metal box) and adhere it to a flat metal surface.
Step 6: Install New Assembly
Twist the sockets back into the new housing. Tuck the wires, align the guide pins, and push the new tail light assembly into place until it clicks.
Step 7: Secure and Finish
Reinstall and tighten the two 8mm mounting bolts. Close the tailgate and test all functions (brake, turn signal, reverse) to ensure proper operation.
Common Issues & Solutions
1. Tail light does not turn on after installation
Please first check whether the wiring harness connectors are properly connected and fully seated. Inspect the pins inside the connector to ensure none are bent or misaligned.
If any pins are bent, you may carefully straighten them using a paper clip or other small precision tool, then reconnect the plug securely.
2. Swap test
If the tail light still does not illuminate, try swapping the left and right tail lights to determine whether the issue is related to the light unit itself or the vehicle wiring.
3. Condensation inside the tail light
Condensation may occur due to temperature differences, which is a normal physical phenomenon. After the tail light has been operating for a period of time and the internal temperature stabilizes, the moisture will naturally dissipate.
This does not affect brightness, performance, or the lifespan of the tail light.
