2016 Mazda6 Map Lights
Gently Pry Out Lens Cover
Remove Tabs - Rear Edge
This automotive maintenance tutorial was specifically written to assist owners of the third generation (2014, 2015, 2016, 2017 and 2018) Mazda Mazda6 sedan in changing a burnt out map light bulb in the overhead console.

Owners of other Mazda vehicles such as the Mazda2, Mazda3, Mazda5, CX-3, CX-5, CX-7, CX-9, and the MX-5 Miata may also find these DIY instructions to be helpful.

The compatible replacement festoon or miniature "fuse" type light bulb is part number DE3175 which is available from various manufacturers such as Sylvania, GE, Philips and JDM.

You can also use a compatible LED unit.

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

Pull Back Electrical Contact
Remove Old Light Bulb
To prevent from scratching the plastic surfaces, either use a thin plastic pry bar tool or wrap the tip of your flathead screwdriver with a thin micro fiber cloth.

Insert the blade of the screwdriver in between the lens cover and the overhead console near the front edge (closest to the windshield).

Gently pry out the lens cover. You might need to re-insert the screwdriver on the other side of the lens cover.

Try to avoid using excessive force. The lens cover should pop out relatively easily.

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

The old light bulb was marked as part number 8A KHA12V8W4.

Line up the lens cover with the overhead console.
