Installing 05-09 Mustang Turn Signal Bulbs & Lenses

In this edition of writeups, we go over the installation process of adding front turn signals to your 2005-2009 Mustang. Installation can be done without even lifting the car in the air.

  • Tools Required:
    Phillips Screwdriver

If you begin with the driver’s side, you’ll want to turn the wheel all the way over to the passenger side to gain access to the screws holding the inner fenderwell on. Remove them using a phillips head screwdriver along with the one push pin.

Once all three screws are removed, you can peel back the inner fenderwell and gain access to the turn signal lens behind the bumper cover. Now you’ll work on removing the stock turn signal lens. There are two white pins holding the turn signal to the bumper cover. Squeeze one pin at a time and gently pull the lens away to release it from the bumper.

Now, you’ll want to remove the stock bulbs from the turn signal lens before completely removing it from the vehicle. There are two separate bulbs in the lens. (3157 and 194 bulb) Grasp each bulb and turn it counter-clockwise to free it from the housing. The lens should be free now. Remove it from underneath the bumper. It helps to have an extra set of hands here

We are now ready to re-install the new turn signal lens. You first want to find the tab behind the bumper cover. This will help you guide the new turn signal lens into place. The tab is shown below.

Slide the new lens in through the opening in the fenderwell. Align the tab on the new lens with the slot on the bumper cover as shown below.

Secure the other end of the lens with the white pins as shown below.

One of the last steps is to install the new 3157 and 194 Chrome-Amber Bulbs. Using latex gloves, remove the stock bulbs and re-install the chrome amber ones. Then place them in the housing and turn them clock wise to secure them in the new lens. It is important to not touch the glass portion of the bulb with your exposed fingers. The oils from your skin can prematurely wear out the bulb. Once your bulbs are in, turn on your turn signals to ensure they work.

Finally, re-install the inner fenderwell screws to complete your installation. Now you can enjoy the clear look while staying DOT legal. The different turn signal lens and bulb packages can be found on our site here: http://www.stangmods.com/Mustang-Clear-Turn-Signal-Lenses-Side-Markers-s/157.htm

Installing Webelectric’s 05′-09′ Mustang Plug-In Sequential Turn Signals

In this writeup we will go over the installation process of our very popular 2005-2009 Mustang Plug in Sequntial kit. Installation is very simple and requires only a couple of basic tools.

Tools Required:

  • 7/16″ Deep Socket
  • Flat head screw driver

First you’ll want to remove the black trim panel from inside the trunk area. Start by removing the twist off screw and push pin as circled below. Use the flat head screw driver to gently pry out the push pin. Repeat on the other side of the vehicle.

Next use your flat head screw driver and remove the two push pins as shown below. Again, gently pry out the pins to avoid any damage.

Take your 7/16 deep socket and remove the three nuts located on the inside of the trunk as shown below. These nuts hold the tail lamp onto the vehicle.

Once you’ve removed all three nuts, you are ready to remove the tail lamp and harness from the vehicle. Depress the tab on the grey harness plug and separate the connectors.

Now, gently pull the tail lamp away from the body of the vehicle and work the harness grommet out of its location using the flat head screwdriver as shown below. Once its free, pull the entire tail lamp and harness completely out.

With the tail lamp out from the vehicle, place it on a flat work bench and begin removing the light sockets by turning them counter-clockwise. You must also remove the socket for the reverse lamp. Finally, the harness is attached to the tail lamp with a white push pin. Remove it gently and free the harness from the tail light.

At this point we are almost done with the first side. Pull the bulbs out of the OEM harness and plug them back into the sequential harness. Before you re-install the new sequential harness, it is important to note the correct position. Each socket is pre-labeled with the numbers 1,2,3. Socket 1 should be installed in the inner most lens, socket 2 in the middle lens, and socket 3 on the outermost lens.

The orientation for the driver’s side tail lamp is shown below:

The orientation for the passenger side tail lamp is shown below:

The new sequential harness contains the white push pin. Remember to place it back in to secure the harness to the tail lamp.

To finish up the installation, re-route the harness with the grey connector through the body of the vehicle and plug it back in. Then, secure the black grommet and re-install the tail lamp. Re-attach the (3) bolts holding the tail lamp to the vehicle. Once you have completed the installation on the opposite side, place the black trim piece in place and re-attach the plastic push pins to complete your installation.
