The GMC Yukon is a model of full-size SUVs manufactured by General Motors and its subsidiary, GMC. Introduced in 1970 as a trim level of the Chevrolet Blazer, it has been labeled “the original premium SUV.” The Yukon is the oldest SUV nameplate still in use today by GM.

The GMC Yukon is a large, roomy, powerful and promising full-size SUV that offers a lot more functionality than the average SUV on the market. The latest model boasts of Xenon High-Intensity Discharge (HID) headlamps that provide adequate light during night driving. 

Bulb Type Used

Depending on the model year, the GMC Yukon uses different bulb types for its high beams, low beams, and fog lights. Bulbs that have been used in the past for the low beam headlights include 9006, H11, H6054, 9008, D3S, and 9005.

For its high beam headlights, bulbs used include 9005, H6054, and 9008. The fog lights come with either an H3-55W, PSX26W, PS24WFF, 880, 894, or 9145 bulbs. 

Upgrading from factory bulbs to aftermarket LED/HID

Before upgrading to LEDs or HIDs, it’s important to ensure that you read the fine print. You can ask the salesperson or take a look at the labels yourself.

Upgrades may sometimes require you to buy more than one package. LED conversion kits for halogen headlights can cost you anywhere between $100 and $300 for a set. If you don’t have the expertise to install them, have a professional do it for you. 

Advantages of upgrading to LED/HID technology

  1. Better light at night
  2. Longer lifespan
  3. Easy to install.
  4. Better aesthetics
  5. Easier to keep up with trends.

Installing new bulbs

The GMC Yukon is a large SUV, and has 5 bulbs used for the license plate lights. These are all of the bulbs needed for this “How-To” article:

1) License Plate Light Bulb (3157NA)

2) Back-Up Light Bulb (3156)

3) Brake Light Bulb (3057/ 3357NA or # 7425NA )

First, you must choose which light bulb type to buy that matches your preference. The 3157NA bulb fits in either socket. If you bought LED’s, then go with the 3057/3357NA because it will not be as bright as the stock 3157 bulb.

  • Step 1 : Open Hood

  Pry up on the hood release handle to open the hood, and secure it with a clip.

  • Step 2: Locate Bulb Socket for License Plate Lights

 Remove the socket from its location by turning counter clockwise.

Note: Some sockets have a “Notch” in them that will fit over a locking tab of another part. Be aware if you are replacing these bulbs, is that they may fall out of place unless locked into position.

  • Step 3: Remove Old Bulb from Socket

Push down on bulb’s small metal tang/tab/clip, which is located at the top of the bulb socket behind where the bulb sits in place. The bottom of this metal tang/tab/clip will go through a hole in the top of the socket.

Pull the bulb out by grasping it with your thumb and pointer finger (in an “OK” hand sign).

 Push new bulb into socket until metal tang/tab/clip locks into place. This is what it should look like:

  • Step 4: Put the License Plate Light Bulb Socket Back into Location and Turn Clockwise

 Twist socket back into original location and turn clockwise to lock in place.

  • Step 5: Locate Bulb Socket for Back-Up Lights, Brake Lights, and Reverse Lights

To access this socket, you must first remove part of the interior’s lower trim panel located below where the steering wheel is at.

 Insert a flat-head screwdriver between the trim panel and the bottom of the dashboard. Pry up gently until you hear/feel the panel release its locking tabs.

Grab panel by upper edge and pull out toward driver’s door.

 Turn bulb socket counter clockwise to remove from its location in dashboard. The back-up light socket will look like this:

  • Step 6: Remove Old Bulb from Socket

Push down on little metal tang/tab/clip, which is located at base of bulb socket behind where bulb sits in place. The bottom of this metal tang/tab/clip will go through a hole in top of socket (see photo above).

 Pull bulb out by grasping it with your thumb and pointer finger (in an “OK” hand sign).

  • Step 7: Put the Back-Up Light Bulb Socket Back into Location and Turn Clockwise

Twist socket back into place and turn clockwise to lock in place.

 Push new bulb into socket until metal tang/tab/clip locks onto top of new bulb.

  • Step 8: Locate Bulb Socket for Brake Lights, Reverse Lights, Third Brake Light

To access this socket, you must first remove part of center console storage drawer unit located at front passenger seat. The back will look like this pic below after removal  and the brake light is the middle one on top row.

Once the drawer unit is out of the way, you will find two bulbs in parallel. The back-up light bulb is on one side and the brake/reverse/third brake light bulb is on the other side.

Turn socket counter clockwise to remove from its location in center console storage area. This bulb socket will look like this:

  • Step 9: Remove Old Bulb from Socket

Push down on little metal tang/tab/clip, which is located at base of bulb socket behind where bulb sits in place. The bottom of this metal tang/tab/clip will go through a hole in top of socket (see photo above).

Pull old bulb straight out by grasping it with your thumb and pointer finger (in an “OK” hand sign).

  • Step 10: Put the Brake/Reverse/Third Brake Light Bulb Socket Back into Location and Turn Clockwise

 Twist socket back into place and turn clockwise to lock in place.

 Push new bulb into socket until metal tang/tab/clip locks onto top of new bulb.

  • Step 11: Locate New LED Light Strip and Pull Straight Out

You will need to push aside the wiring harness and find the new LED light strip. The strip is held in place with two metal clips (see photo below). Push aside each of these metal clips using your thumb and pointer finger, then pull out the LED strip by gripping both ends with one hand.

  • Step 12: Unfold LED Strip

 There are no wires on this side of the strip: only a row of LEDs, which will fit into back-up light socket.

 Ensure that short wire coming off from end of strip is attached to left wire when facing front of vehicle  (see photo below).

  • Step 13: Insert LED Strip into Back-Up Light Socket and Twist Clockwise

Ensure that short wire coming off from end of strip is attached to left wire when facing front of vehicle  (see photo below).

Push LED strip into socket and twist clockwise to lock in place.

  • Step 14: Working on the Inner Fender Well

The large metal clips holding the wiring harness should be just above your head when laying down on driver’s side inner fender well (see photo below)

The two metal clips holding back-up light strip onto bottom edge of black plastic underpanel will be within reach (see photo below). Just push/pull each metal clip outward and free up the LED strip.

  • Step 15: Re-attach Wiring Harness

Now, re-attach the wiring harness to the new LED strip. Push aside metal clips and push black tab with wires back into place.

  • Step 16: Close Inner Fender Well

 Open up and close inner fender well so its D shaped opening is facing you (see photo below)

Once this opening is facing you, carefully feed LED strip out through this hole. Ensure that no part of strip touches any sharp edges or plastic parts. If it does touch anything, then cut off bent/damaged part of strip with wire clippers  and solder wires again to create new connection.

  • Step 17: Re-attach Underpanels

There are four upper and four lower black plastic underpanels that need to be re-attached into place. The four upper clips are attached to the underside of the inner fender liner (see photo below).

Carefully push aside metal tabs and place panel in original location, pushing plastic tab back into place. Repeat for each underpanel.

Be careful not to pinch LED strip between edge of under panel and rubber gasket when putting panels back into place. Make sure strip is fully pushed behind gasket when positioning panels in the original location.

  • Step 18: Re-connect Battery Cables

Once all eight underpanels are back in their proper position, go ahead and replace both battery cables onto batteries (+/positive to +/positive and -/negative to -/negative).

Take a look over your work to double check that no wires, panels or LED strip is in any way pinched. If all looks well, then you can re-connect the negative battery cable and start up the vehicle.

Additional Equipment

  1. Latex gloves to prevent you from touching the bulbs with your bare fingers. 
  2. Screwdriver.
