The Chrysler Crossfire side marker requires a 12961 bulb size for proper installation and function within the lighting assembly. Data for the specified component covers the range from 2005 to 2006.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chrysler Crossfire uses the 12961 bulb for both front and rear side marker positions across the 2004-2008 model years.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor with a W2.1x9.5d base.
The T10 designation refers to a tubular bulb body approximately 10mm wide, a standard sizing classification in automotive lighting.
The W2.1x9.5d base type is a wedge-style base, meaning the bulb is held in its socket by the tension of the base itself rather than by a bayonet or screw mechanism.
The 12961 operates at 12 volts and 5 watts, which is consistent with low-current marker lighting applications rather than high-intensity functions such as headlamps or brake lights.
Because the Chrysler Crossfire (2004-2008) uses the same 12961 bulb in all four side marker positions, front and rear replacements are interchangeable with one another.
The W2.1x9.5d base is a specific wedge standard, and substituting a bulb with a physically similar but dimensionally different wedge base risks poor socket contact or fitment failure.
The 12961 is a Philips-branded part, though the T10 W2.1x9.5d 12V 5W specification is a widely adopted standard, meaning equivalent bulbs from other manufacturers may share the same electrical and physical characteristics.
