Additional Notes

The 168 bulb is the sole clock light bulb size listed for the Chevrolet C-Series Pickup across the 1985-1986 model years.
The 168 is an ANSI-standardized bulb used in both the United States and Canada, ensuring consistent availability across North American markets.
This bulb follows the T10 miniature wedge form factor, which uses a wedge-shaped base that seats directly into a socket without a separate metal base or pins.
The 168 operates at 12 volts with a power draw of 4.9 watts, placing it in the low-wattage range typical of instrument and indicator lighting applications.
The T10 wedge base is shared across a wide range of automotive interior lighting applications, though fitment compatibility depends on the specific socket design of each vehicle.
