Additional Notes

The 168 bulb is an ANSI-standardized type used across North American markets, operating at 12 volts with a power draw of 4.9 watts.
The 168 follows the T10 miniature wedge form factor, which uses a wedge-shaped base rather than a pin or bayonet fitting, allowing it to be held in place by the socket walls alone.
The Scion xA uses the 168 bulb for its parking lights across the 2004-2006 model years.
The T10 wedge base is shared by several bulb types in the same family, meaning physical fitment in the socket does not guarantee electrical compatibility; wattage and voltage ratings should match the original specification before substitution.
