2015 Lancer Map Lights
Insert Flathead Screwdriver
Pry Out Lens Cover
This automotive maintenance tutorial was specifically written to assist owners of the eighth generation (2008, 2009, 2010, 2011, 2012, 2013, 2014 & 2015) Mitsubishi Lancer in changing a burnt out map light bulb in the overhead console or upgrading both bulbs to brighter LED units.

Owners of other Mitsubishi vehicles such as the Mirage, Lancer Evolution ("Evo"), Outlander, 3000GT, Diamante, Eclipse, Endeavor, Galant, Montero, ASX, Triton L200 and Raider may also find these DIY instructions to be helpful.

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

You can also use a compatible LED unit.

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

Lens Cover Removed
Old Bulb Exposed
Pull Back Metal Tab
To prevent from scratching the plastic surfaces, you may choose to cover the tip of your screwdriver with a thin micro fiber cloth.

Insert the blade of the small flathead screwdriver in between the overhead console and the inner edge of the lens cover.

Gently pry out the inner edge of the lens cover and then remove the plastic tabs on the outer edge.

Set the lens cover aside in a safe place.

If the old bulb was recently turned on, be careful since it might still be hot enough to burn your fingers.

Gently pull back the metal electrical contact until the old bulb can be removed from the socket.

Toshiba Part # A12V8W
Empty Bulb Socket
Insert New # DE 3175
The OEM bulb in this 2015 Mitsubishi Lancer sedan was a Toshiba brand part number A12V8W.

Pull back the metal electrical contact and Insert a new # DE3175 bulb in to the socket.

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


Press Button - Test Bulb
Re-Insert Plastic Tabs
Line Up Retaining Clips
Test the new bulb by pressing the white plastic "On/Off" button.

Re-insert the two plastic tabs on the outer edge of the lens cover in first.

Pop In Lens Cover
Slide Switch To "Door"
Testing New Map Lights
Gently pop in the two retaining clips on the inner edge of the lens cover.

Slide the switch to the "Door" position so that the two map lights will turn on when ever a passenger door is opened.
