The Pontiac Sunfire side marker requires a 194 bulb size for proper illumination and replacement within the lighting assembly. Data for the specified component covers the range from 1995 to 2005.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Pontiac Sunfire uses the 194 bulb for both the front and rear side marker positions across all model years from 1995-2005.
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 194 bulb follows the T10 miniature wedge form factor, which uses a wedge-shaped base rather than a metal contact pin, allowing it to be inserted directly into a compatible socket without a separate connector.
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 relatively low power, which is typical for side marker applications where continuous illumination is required without significant electrical load.
Because the front and rear side marker positions share the same 194 bulb specification on the Pontiac Sunfire, a single bulb type services both locations on the vehicle.
The T10 wedge base format of the 194 is a widely used platform, and various aftermarket alternatives including LED replacements are commonly produced in this form factor, though socket and voltage compatibility would need to be confirmed before substitution.
