Additional Notes

The Chrysler Crossfire uses the 1156 bulb for the back up light across all listed model years, spanning 2004-2008.
The 1156 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized industry standard used across the United States and Canada.
This bulb operates on a single filament, which is typical for functions requiring only one lighting state, such as reverse illumination.
The 1156 uses a BA15s bayonet base, a single-contact mount where the bulb is inserted and twisted to lock into place.
The bulb is rated at 12 volts, consistent with standard automotive electrical systems.
At 21 watts, the 1156 falls within the mid-range of common single-filament automotive bulbs, producing a moderate level of output suited for reverse lighting.
The BA15s base designation indicates a single-contact bayonet fitting, which is not interchangeable with the BA15d base used on dual-filament bulbs despite the similar physical size of the mount.
