2013 Highlander Dome Light
Pry Out Lens Cover
Lens Cover Removed
This automotive maintenance tutorial was specifically written to assist owners of the second generation (2008, 2009, 2010, 2011, 2012 & 2013) Toyota Highlander in changing a burnt out overhead dome light bulb.

Owners of other Toyota or Scion vehicles such as the Tacoma, Corolla, Yaris, Prius, Camry, RAV4, Tundra, Sienna, FJ Cruiser, Venza, Avalon, 4Runner, Sequoia, xB, xD, tC, iQ and FR-S may also find these DIY instructions to be helpful.

A replacement festoon or "fuse" style dome light bulb is part number DE3175 from manufacturers such as Sylvania and GE.

You can also use a brighter LED bulb.

(Some Highlander models might instead have the # 168 miniature wedge base bulb for the dome light.)

The only tool needed to change the bulb is a small flathead screwdriver used to pry out the translucent plastic lens cover.

Old Dome Bulb Exposed
Pull Back Electrical Contact
Remove Old Light Bulb
To prevent from scratching the plastic surfaces, you may choose to cover the tip of your screwdriver with a thin micro fiber cloth.

Carefully insert the blade of the small flathead screwdriver in to one of the two notches on the front edge of the lens cover.

Gently pry out the lens cover and set it aside in a safe place.

Pull back on the flexible electrical contact on the left (driver) side to release the old bulb from the socket.

Old # DE3175 Festoon Bulb
Insert New DE3175 Bulb
Pop In To Socket
Insert a new # DE3175 festoon style bulb in to the right side of the socket first and then gently pop in the left side.


New Bulb Installed
Slide Switch To "On"
Insert Tabs On Rear
Test the new dome light bulb by sliding the switch to the "On" position.

(Tip - If you are replacing the OEM incandescent bulb with a brighter LED unit and it won't work at first, try flipping the bulb around in the socket.)

Insert the two tabs on the rear edge of the lens cover in to the housing first.

Pop In Front Edge
Lens Cover Replaced
Slide Switch To "Door"
Gently pop in the front edge of the lens cover.

Slide the switch to the "Door" position so that the dome light will turn on whenever a passenger door is opened.
