This automotive "how-to" guide was specifically written to assist owners of the 1st generation (2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014 & 2015) Mazda CX-9 crossover SUV in replacing a burnt out courtesy step light bulb at the bottom of the interior door panel.

Owners of other Mazda vehicles such as the MAZDA2, MAZDA3, MAZDA6, MX-5 Miata, RX-8, MAZDASPEED3, MAZDA5, Tribute SUV, and CX-7 crossover may also find this guide to be helpful.

A replacement light bulb for the courtesy step lights in the door panels of a '07-15 Mazda CX-9 is part # 2825 available from manufacturers such as Sylvania, GE, Phillips, Wagner, PIAA and Eiko.

You can also choose to use a brighter 2825 LED bulb.

The tools needed to replace the courtesy step light bulbs include a small flathead screwdriver and a set of needle nose pliers or tweezers.

Insert the blade of the flathead screwdriver between the edge of the translucent light bulb cover and the door panel. Gently pry out the lens cover and place it aside in a safe place.

If you are replacing the OEM bulb with a colored bulb or an aftermarket LED bulb, use gloves or needle nose pliers to safely pull out the original bulb which may be very hot.

Push in a new # 2825 wedge base bulb into the courtesy step light socket. Since the car door is open, the bulb should immediately light up.
