2015 Outlander Sport Dome Light
Small Notch - Rear Edge
Insert Flathead Screwdriver
This automotive maintenance tutorial was specifically written to assist owners of the third generation (2011, 2012, 2013, 2014, 2015, 2016 and 2017) Mitsubishi Outlander Sport in changing a burnt out dome light bulb in the overhead housing attached to the headliner.

Owners of other Mitsubishi vehicles such as the Lancer, Outlander, Mirage, ASX, RVR, Galant, I-MIEV, Montero, Eclipse, 3000GT, Endeavor, Raider, Diamante, Attrage, Carisma, Colt, Grandis, Magna, Pajero and the Space Star may also find these DIY instructions to be helpful.

The compatible replacement festoon or "fuse" style light bulb is part number DE3175.

You can also use a brighter DE3175 LED bulb.

The only tool needed to access and replace the light bulbs is a small flathead screwdriver or a small plastic pry bar tool.

Lens Cover Removed
Old Bulb Exposed
Pull Back Electrical Contact
I recommend sitting in the second row of passenger seats for easier access to the dome light bulb housing.

To prevent from scratching the plastic surfaces, you can either wrap the tip of your screwdriver in a thin micro fiber cloth or use a plastic pry bar tool.

Insert the blade of the screwdriver in to the small notch on the rear edge of the lens cover.

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

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

Remove Old Light Bulb
Old # DE 3175 Bulb
Install New Light Bulb


Pull the old light bulb straight out of the socket.

Insert a new number DE3175 festoon bulb in to the socket.

(Tip - If you are installing an LED bulb and it doesn't work at first, try flipping it around the other way in the socket.)

Line Up Lens Cover
Gently Pop In Lens Cover
Test New Dome Light Bulb
Line up the lens cover and gently snap it back in to place.

To test the new dome light bulb, slide the switch to the "On" position.

I recommend leaving the switch in the "Door" position so that the dome light will turn on when ever a passenger door is opened.
