Additional Notes

The GMC Savana uses the 194 bulb for the ash tray across all listed model years, spanning 1996-2002.
The 194 is an ANSI-standardized bulb type, meaning its specifications are governed by a recognized North American standard applicable in both the United States and Canada.
The bulb follows the T10 form factor, a miniature wedge-base design that seats without a separate locking mechanism, relying instead on tension from the socket walls to hold it in place.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger and commercial vehicles.
At 3.78 watts, the 194 draws a relatively low amount of power, which is typical for interior illumination applications such as ash tray lighting.
The T10 wedge base is a widely produced form factor, and the 194 designation is shared across many vehicle makes and models, which contributes to broad retail availability.
When sourcing a replacement, the bulb must match the 194 designation specifically, as other T10-based bulbs may carry different wattage ratings and would not be electrically equivalent.
