Additional Notes

The 194 bulb is the sole glove box bulb size listed across all Chevrolet Silverado model years in these specifications, covering 1999-2007.
The 194 bulb follows the ANSI standard recognized in both the United States and Canada, placing it within a widely adopted North American lighting classification system.
It uses a T10 miniature wedge base, a socket type that requires no locking pins or bayonet turns, as the wedge-shaped base itself holds the bulb in place within the socket.
The bulb operates at 12 volts, which is consistent with standard automotive electrical systems.
Its power draw is rated at 3.78 watts, placing it in the low-wattage category typical of interior courtesy and illumination lamps.
For the 2003-2007 Chevrolet Silverado, the 194 glove box bulb applies to the 1500 and 3500 sub-models only, meaning the 2500 sub-model is not covered by this fitment in the specifications.
For the 1999-2002 Silverado, the 194 bulb is listed without any sub-model restriction, indicating it applies across the available configurations for those years.
The sub-model restriction introduced from 2003 onward represents a fitment distinction that makes direct interchangeability assumptions between the 2002 and 2003 model years inadvisable without confirming the specific sub-model.
