Installation Instructions
Rear Sidemarker Installation
Step 1 – Access the rear sidemarker
If you have a non-marring trim tool, you may be able to remove the rear sidemarker by inserting the tool at the back of the sidemarker and pushing forward toward the front of the vehicle. If successful, proceed to Step 5.
If a trim tool is not available, remove the three screws in the wheel well using a Phillips screwdriver or socket with bit.
Step 2 – Remove the sidemarker
Using a 10mm socket wrench, remove the two nuts on the back of the sidemarker. Push the sidemarker out from the bumper.
Step 3 – Remove the factory bulb
Twist the factory bulb socket counterclockwise to remove it from the sidemarker, then remove the bulb.
Step 4 – Install the new LED sidemarker
Plug the connector from the new Diode Dynamics LED sidemarker into the socket. Check polarity by activating the unlock button—if the sidemarker does not illuminate, flip the connector 180 degrees.
Step 5 – Reinstall the rear sidemarker
Twist the plug back into the new sidemarker to seal it. Place the sidemarker back into the bumper and tighten the nuts on the rear. Do not overtighten. Reinstall the wheel well liner and screws. Repeat for the opposite side.
Front Sidemarker Installation
Step 6 – Access the front sidemarker
Using a 7mm socket wrench, remove the three screws in the wheel well. Pull the wheel well liner back just enough to access the sidemarker.
Step 7 – Remove the front sidemarker
Pull back on the bumper to access the sidemarker. Press the clip toward the front of the vehicle and push the sidemarker out of the bumper.
Step 8 – Install the new LED sidemarker
Twist the factory plug counterclockwise to remove it from the sidemarker and remove the bulb. Plug the connector from the new LED sidemarker into the socket. Verify polarity and flip the connector 180 degrees if needed.
Step 9 – Reinstall the front sidemarker
Twist the plug back into the new sidemarker to seal it. Place the sidemarker back into the bumper, clip it into place, and reinstall the wheel well liner and screws. Repeat for the other side.
