Additional Notes

The Chevrolet Express uses the 194 bulb for the license plate position across all model years from 1996 to 2022.
The 194 is a miniature wedge-type bulb, classified under the T10 form factor, which refers to a tubular bulb with a width of 10 eighths of an inch.
The wedge base design means the 194 bulb is held in place by the socket itself rather than by a separate metal base with pins, which is a common trait of low-current indicator and courtesy lighting applications.
The 194 operates at 12 volts and draws 3.78 watts, placing it in the low-wattage category typical of exterior illumination bulbs that run continuously with the vehicle's lights.
The 194 carries ANSI standardization recognized in both the United States and Canada, meaning the bulb specification conforms to a defined interindustry standard rather than a proprietary sizing.
Because the 194 is an ANSI-standardized wedge bulb, it is produced by multiple manufacturers and is widely available as a direct replacement without modification to the socket.
LED replacements in the T10 wedge format are physically compatible with the 194 socket, though polarity sensitivity is a known characteristic of LED wedge bulbs in DC circuits.
The 194 and the closely related 168 bulb share the same T10 wedge base, but the 168 operates at a higher wattage of 4.9 watts, making the two bulbs non-equivalent despite their physical similarity.
