2015 4Runner Fog Light
Look Under Bumper Cover
Push Tab To Release
This automotive maintenance tutorial was specifically written to assist owners of the fifth generation (2010, 2011, 2012, 2013, 2014, 2015 & 2016) Toyota 4Runner SUV in changing a burnt out fog light bulb in the front bumper cover.

Owners of other Toyota, Lexus or Scion vehicles such as the Yaris, Corolla, Matrix, Prius, Camry, RAV4, Sienna, Tacoma, Tundra, FJ Cruiser, Venza, Highlander, Avalon, Sequoia, Land Cruiser, IS 250, ES 350, GS 350, tC, xB, xD, iQ and FR-S may also find these DIY instructions to be helpful.

The replacement light bulb part number is H16 Type 2 which are available from various manufacturers such as Sylvania, GE, Eiko, PIAA and Noya.

If you would like to have brighter fog lights, install some compatible replacement H16 LED bulbs.

No tools are needed to access and replace the fog light bulbs since they can be reached from under the bumper.

Power Plug Removed
Base of Old Fog Light Bulb
1/4 Turn Counterclockwise
The owner's manual recommends removing the four wheel well fasteners to access the fog light bulb housing.

I found that it was very easy to just reach in under the front bumper cover to access the rear of the fog light housing.

If you do choose to go in behind the wheel well liner, you'll need a 10mm socket with a 1/4" drive ratcheting wrench or a Phillips head screwdriver to remove the four fasteners along the outer edge.

Swing your head under the front bumper cover and locate the old fog light bulb.

Press in the tab on the electrical connector to release it before sliding the plug straight off the base of the old light bulb.

Rotate the base of the old light bulb 1/4 turn counterclockwise before pulling it straight out of the housing.

Remove Old H16 Type 2
Empty Bulb Socket
Insert New H16 Type 2
Try to avoid touching the glass part of the new halogen bulb with your fingers or anything greasy in the engine bay.

If you do get the new bulb dirty, wipe it clean with a paper towel moistened with rubbing alcohol.

Be sure to buy an H16 Type 2 bulb that is shaped like an "L" similar to a traditional headlight bulb on most cars.

If you by an H16 LED bulb, make sure it is the correct "Type 2" shape.

(There is also another type of H16 bulb that looks more like a "T" with a retaining clip on both sides of the base. It will not fit in to the fog light bulb housing.)

1/4 Turn Clockwise - Lock
Push On Power Plug
Test New Fog Light Bulb
Insert the new H16 Type 2 halogen bulb in to the socket and rotate it 1/4 turn clockwise to secure it in place.

Push the power plug straight on to the base of the new bulb until it clicks securely in to place.

Test the new light bulbs by turning on the headlights and then activate the fog light switch.

Be sure to record the bulb change in your vehicle's service records.
