Additional Notes

The 9006 is a single-filament halogen bulb operating at 12 volts and 55 watts, built to the ANSI standard recognized in the United States and Canada. It uses a P22d base, which is a push-and-twist locking base type designed to seat securely in the housing socket.
The Scion xA uses the 9006 bulb size across all listed model years for the front fog light position, covering the 2004-2006 range without variation.
Because the 9006 is a single-filament bulb, it serves only one lighting function per unit. It is not interchangeable with dual-filament bulbs such as the 9007 or H13, which share a similar physical form but carry a different pin configuration and wiring arrangement.
The P22d base of the 9006 is not compatible with the P29t base found on related bulbs like the 9005. Although the 9005 and 9006 are often grouped together due to their similar appearance, their base configurations differ and they are not cross-compatible without modification.
