Additional Notes

The Chevrolet SSR uses the 194 bulb for the license plate position across all documented model years, spanning 2003-2006.
The 194 is a miniature wedge-base bulb, classified under the T10 form factor, which refers to a tubular glass envelope roughly 10 eighths of an inch wide.
The wedge base design means the bulb is held in place by the socket gripping the glass pinch at its base, with no separate metal base or pins involved.
The 194 operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
At 3.78 watts, the 194 draws a relatively low amount of power, which is typical for a license plate illumination application where output requirements are modest.
The 194 carries ANSI standardization recognized in both the United States and Canada, meaning the specification conforms to a defined industry standard rather than a proprietary sizing.
Because the 194 is an ANSI-standardized T10 wedge bulb, it is produced by multiple manufacturers, and physical fitment is governed by the standardized wedge base rather than brand-specific tolerances.
The consistent use of the same bulb size across all four model years of the SSR indicates no mid-cycle revision to the license plate lamp assembly during the vehicle's production run.
