Owners of other Mitsubishi vehicles such as the Outlander Sport, Eclipse Cross, Mirage, Mirage G4, Lancer, ASX, Montero Sport, Pajero, Xpander, Strada and RVR may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) light bulb was marked as part number Toshiba A12V8W.

The compatible replacement festoon style light bulb is part number DE3175 which is available from various manufacturers such as Sylvania, GE, Maxell, PIAA and Eiko.

If you'd like to have brighter map lights that will also last much longer before burning out like the traditional incandescent light bulbs, install some DE3175 LED units.

The only tool needed to access and replace the bulbs is a flat head screwdriver or a plastic pry bar tool.

To help prevent from scratching the plastic surfaces, I recommend either covering the tip of your screwdriver with a thin micro fiber cloth or instead use a plastic trim panel removal tool.

Carefully insert the blade of the screwdriver in between the inner edge of the lens cover and the overhead console (close to the "Off / On / Door" switch).

Do NOT pry along the outer edge of the lens cover. There are two plastic tabs on the outer edge of the lens cover that could be easily broken.

Very gently pry out the inner edge of the lens cover to release the two "C" shaped retaining clips.

You may need to remove and reinsert the flat head screwdriver at another point on the inner edge of the lens cover to release both retaining clips.

Try to avoid using excessive force. The inner edge of the lens cover should pop out relatively easily.

Set the lens cover aside in a safe place.

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

Very gently pull back the flexible metal electrical contact to release the old bulb from the socket.

Try to avoid bending either metal electrical contact.

It can be replaced with the very common DE3175 festoon style light bulb which is available from various manufacturers such as Sylvania, Philips, GE, PIAA and Eiko.

If you'd like to have much brighter map lights that will also last longer, install some compatible replacement DE3175 LED units.

Make sure the new bulb is securely installed in between the two metal electrical contacts.

If the new bulb seems loose, try bending the metal electrical contacts back into the straight down position.

I recommend testing the new light bulb before you reinstall the lens cover.

Press the white plastic "On / Off" button to test the new light bulb.

Tip - If you installed an LED bulb and it doesn't work, try removing it from the socket, rotating it 180 degrees and pushing it back into the socket. Some LED bulbs are "polarized" and will only work when the "+" positive and "-" negative electrical contacts are in the correct orientation.

Line up the lens cover with the light housing in the overhead console.

First, reinsert the two plastic tabs on the outer edge into the opening.

Make sure the lens cover is properly re-installed.

To test the new light bulbs again, push on the outer edge of the lens cover to activate the "On / Off" button.

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