The Mazda CX-7 front and rear side marker bulbs utilize a 168 bulb size, with alternative designation 12961 available for replacement applications. The replacement chart covers vehicle production spanning 2007 to 2012.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mazda CX-7 uses two distinct bulb sizes across its production years for both front and rear side markers: the 168 and the 12961.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor with a W2.1x9.5d base, rated at 12V and 5W.
The 168 is an ANSI-standard bulb sold across the US and Canadian markets, also a T10 miniature wedge type, rated at 12V and 4.9W.
Both the 168 and the 12961 share the T10 miniature wedge form factor and a 12V operating voltage, placing them in the same general bulb family despite carrying different part numbers.
The wattage between the two bulbs differs slightly, with the 12961 rated at 5W and the 168 rated at 4.9W.
For the 2007-2011 Mazda CX-7, both the front and rear side marker positions call for the 12961 bulb.
The 2012 Mazda CX-7 specifies the 168 bulb for both the front and rear side marker positions, representing a change from the 12961 used in prior model years.
The front and rear side marker positions share the same bulb size for every model year in these specifications, meaning no asymmetry exists between front and rear fitment within a given year.
