In this write-up we add a set of clear rear side markers and red led bulbs to our 2009 Mustang GT. Installation is very simple and takes virtually minutes to do. You can find our rear side marker/LED package here – http://www.stangmods.com/Mustang-Rear-Side-Marker-Lenses-Red-LED-Bulbs-p/00980.htm
- Flat head screwdriver
- Terry Cloth or Towel
The first step is removing the stock side marker. This is done by wrapping the end of a flat head screwdriver with a towel. Insert the end into the small gap where the sidemarker meets the body of the car and gently pull outward.
The sidemarker will be attached to the wiring harness from the vehicle. Depress the tab shown in the picture below and release the harness from the lens.
Now, remove the stock bulb housing from the lens by turning it counter clockwise. This is what you’ll be left with after removing the housing with bulb inside.
Now its time to get the clear lens and LED bulb ready for installation. Simply pull the stock halogen bulb out of its base and insert the new LED bulb. It’s important to note that the LED bulb will fit in the bulb housing two different ways, but only one way is correct. After installing the LED bulb in the small black housing, plug it into the sidemarker wiring harness. Use your key fob and unlock your doors. This will cause the LED bulb to come on. If it does not light up, then flip the position of the LED in the bulb housing.
Once you’ve done this, remove the bulb housing from the wiring harness and re-install it into the new clear side marker as shown below.
We’re almost done at this point. Take your new sidemarker with LED bulb installed and plug the sidemarker wiring harness back in.
The clear lens has an OEM fit. Simply push the lens back into place and you should hear/feel it snap in. It does not require much force to get it on so don’t force things!
Your installation is now complete!
