Install Guide – 2010-2012 Mustang Front Side Markers

When it comes to changing the looks of your mustang, one of the first things that many people do is to start with the small things like lighting. One of the most popular looks with a mustang is to darken the lights around the car with tints or new lenses. Today I am going to install some new marker light lenses into the bumper of a 2011 Ford Mustang GT. The lenses I am changing are the ones on the lower font bumper of the car. Some people call these blinkers, but that is not what they are. The blinkers are built into the headlights on the 10-12 Mustangs and the lights on the bumper are simply running lights.

This installation will take you about an hour barring any issues and it makes things easier if you have someone to help you while you are under the car. You can do this install alone; the only part that helps to have a helper is so someone can hold the lens in the bumper while you put the little nuts back on the backside f the bumper. Let’s get to it!

1. The first thing you need to do is get the car up on ramps or jack stands. Never climb under the car with nothing other than a spare tire jack holding the car up. Once you get the car safely off the ground, move onto step 2.

2. You will need to remove the aero tray on the bottom of the car to expose the oil filter and the underside of the front bumper. If you have an 11-12, you only need to remove four screws on the rear of that tray to access the underside of the car. If you have a 2010, you will need to remove all the screws so you can remove the tray completely.

3. Once you remove that tray, you need to remove the bolt you see in this image between the front tire and the bottom edge of the fender well. You need to remove this bolt so you can pry the liner under the front bumper back enough to reach the turn signal lights.

4. Once you remove that bolt you can pry the fencer liner back enough to see the stock bumper light. It is the part surrounded by a red circle in the photo below. The light is held in with two nuts that were 9mm on the car I used, fasteners vary a bit sometimes so your mileage may vary. These screw off just like any other bolt even though they look like press-on fittings.

5. You need to remove the factory light socket from the light and you can take the bulb out at this point if you want.

6. Once you remove the factory lens, you are ready to slip the new Stangmods tinted or clear lens into the factory bumper hole. I have installed these lights on a 2010 and the factory hardware worked perfectly. On the 2011 GT you see here, the factory hardware was slightly too large to fit on with the wide part of the factory nut facing down as it was on the stock lenses. The fix is as simple as flipping that factory hardware over and tightening the bolts down. Don’t over tighten the bolts or you will break the tabs.

7. Once you have the factory hardware tightened up, you can insert your new amber bulbs, which allows you to stay street legal, and then reattach the factory wire. You will repeat the same process on the other side of the car and you are finished!
