Additional Notes

The Toyota T100 uses the 168 bulb size for its parking lights across all available model years, spanning 1993-1998.
The 168 bulb is an ANSI-standardized type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
This bulb follows the T10 miniature wedge form factor, which refers to a small, wedge-shaped base that is inserted directly into a socket without requiring a separate metal base or bayonet pins.
The 168 operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of parking and marker light applications where continuous illumination is expected without significant electrical load.
The wedge base design of the T10 format means the bulb is held in place by tension from the socket walls rather than a locking mechanism, which affects how it is seated and removed.
Because the 168 is an ANSI-designated bulb, it is interchangeable with other bulbs sharing the same T10 wedge base and matching voltage and wattage ratings, provided those substitutes conform to the same standard.
