Chrysler 300 front and rear side marker bulbs utilize 12961, 1895, and 168 bulb sizes depending on location and model generation. The replacement chart covers 1968 through 2014 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chrysler 300 front side marker positions for 2011-2014 all use the 12961 bulb, a Philips-designated miniature wedge type built on a T10 form factor with a W2.1x9.5d base, rated at 12V and 5W.
The 12961 is a manufacturer part number assigned by Philips rather than an ANSI industry standard designation, which distinguishes it from the 168 and 1895 bulbs also present in these specifications.
The 168 bulb, specified for the 2014 Chrysler 300 rear side marker, follows the ANSI standard recognized in both the US and Canada. It is also a T10 miniature wedge type, rated at 12V and 4.9W.
Although the 12961 and the 168 share the same T10 wedge form factor, their wattage ratings differ slightly, at 5W and 4.9W respectively, and their part number origins differ. These two bulbs are not confirmed as interchangeable within these specifications.
The rear side marker position on the Chrysler 300 does not use a consistent bulb across all listed years. The 2014 model year calls for the 168, while 2011 and 2012 call for the 12961.
The 1895 bulb, used in both front and rear side marker positions on the 1968 Chrysler 300, is a T5 miniature wedge type rated at 12V and 0.9W, making it significantly lower in wattage than either the 12961 or the 168.
The T5 form factor of the 1895 is physically smaller than the T10 form factor shared by the 12961 and 168, meaning the 1895 is not a physical substitute for either of the other two bulbs in these specifications.
The W2.1x9.5d base designation on the 12961 refers to a wedge base with a 2.1mm wire width and a 9.5mm pin spacing, which is the standard base configuration for T10 miniature wedge bulbs in automotive applications.
