The Chrysler Crossfire front and rear turn signal bulbs utilize a 12496 or PY21W bulb size across all positions. The replacement chart covers 2004 through 2008 model years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 12496 is a Philips/Osram part number designating a halogen bulb rated at 12V and intended for specialty automotive applications.
The PY21W is an ECE-standardized bulb used across European and worldwide markets, operating at 12V with a 21W output and a single filament that produces amber light natively.
The PY21W uses a BAU15s bayonet base, an offset-pin fitting that prevents accidental installation of non-amber bulbs into positions requiring a dedicated amber source.
Both bulb types share a 12V operating voltage, meaning the electrical supply requirement is consistent across all listed positions and model years for the Chrysler Crossfire.
The front turn signal position on the Chrysler Crossfire uses the 12496 for 2004 and 2006-2008, while the 2005 model year specifies the PY21W instead.
The rear turn signal position shows a mixed pattern across model years, with the PY21W specified for 2005 and 2007, and the 12496 specified for 2004, 2006, and 2008.
Because the 12496 and PY21W differ in base type and physical construction, the two bulbs are not interchangeable without verifying socket compatibility for the specific model year and position.
The PY21W's amber coloration is built into the bulb envelope itself, whereas the 12496, as a clear halogen bulb, relies on the lens or housing to produce the required amber signal color.
