2014 Corolla Dome Light
Insert Flathead Screwdriver
This automotive maintenance tutorial was specifically written to assist owners of the eleventh generation (2014, 2015, 2016, 2017 and 2018) Toyota Corolla in changing a burnt out dome light bulb in the headliner housing.

Owners of other Toyota, Lexus or Scion vehicles such as the Yaris, 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.

A replacement festoon or "fuse" style light bulb is part number DE3175 which is available from various manufacturers such as Sylvania, GE, Eiko and PIAA.

If you would like to have a brighter dome light, install a compatible DE3175 LED bulb.

The only tool needed to access and replace the dome light bulb is a small flathead screwdriver used to pry out the translucent plastic lens cover.

2nd Notch - Front Edge
Pull Out Lens Cover
To prevent from scratching the plastic surfaces, you may choose to cover the tip of your screwdriver with a thin micro fiber cloth.

Locate the two small notches on the front edge of the lens cover.

Insert the blade of the small flathead screwdriver in to a notch and gently pry out the lens cover. You may need to re-insert the screwdriver in to the other notch.

Try to avoid using excessive pressure, the lens cover should pop out relatively easily.

Set the lens cover aside in a safe place.

Lens Cover Removed
Pull Back Metal Tab
If the old bulb was recently turned on, be careful when you remove it since it might still be hot enough to burn your fingers.

Gently pull back the metal electrical contact to release the old bulb from the socket.

Release Old Bulb
Old # DE 3175 Bulb
Pull the old bulb out of the socket.


Empty Bulb Socket
Insert New DE3175
Insert a new # DE3175 festoon style bulb in to the socket.

Make sure that the new bulb is securely installed.

Test New Light Bulb
Re-Insert Tabs - Rear Edge
To test the new dome light bulb, slide the "On - Door - Off" switch to the "On" position.

Re-insert the two plastic tabs on the rear edge of the lens cover back in to the housing.

Gently Pop In Front Edge
Slide Switch To "Door"
Then gently pop in the front edge of the lens cover.

I'd recommend sliding the "On / Door / Off" switch to the "Door" position so that the dome light will turn on when ever a passenger door is opened.
