Toyota T100 Parking Light Bulb Size

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.
