Additional Notes

The Acura TL uses the 168 bulb for the license plate position across all model years listed in the specifications, spanning 1995-2006 and 2009-2014.
The 168 is a T10 miniature wedge bulb, meaning it uses a wedge-style base rather than a bayonet or screw fitting, and is held in place by friction within its socket.
The bulb operates at 12 volts with a power draw of 4.9 watts, placing it in the low-wattage range typical of license plate and courtesy lighting applications.
The 168 designation follows ANSI standards recognized in both the United States and Canada, indicating a standardized specification for the bulb's electrical and physical characteristics.
The T10 designation refers to the bulb's tubular envelope size, with the number 10 representing a width of ten-eighths of an inch.
The 168 and the closely related 194 are both T10 wedge bulbs, but they differ in wattage; the 168 is rated at 4.9W while the 194 is rated at 3.8W, and substituting one for the other may affect socket compatibility or brightness.
Because the 168 bulb is an ANSI-standardized type, it is a widely available replacement found across many automotive and retail supply channels.
