The Chevrolet SSR side marker requires a 194 bulb size for the specific lighting component located on the exterior of the vehicle. Data for the bulb covers the range from 2004 through 2006.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet SSR uses the 194 bulb for both front and rear side markers across all model years from 2003-2006.
The 194 is an ANSI-standardized bulb type recognized across the United States and Canada, which reflects a widely adopted specification in North American automotive applications.
The 194 bulb follows the T10 miniature wedge form factor, a designation that refers to its tubular glass envelope and wedge-style base, which seats directly into a socket without a separate metal base or pins.
At 12 volts and 3.78 watts, the 194 operates within the standard low-voltage electrical architecture found in passenger vehicles, drawing a relatively low current consistent with marker light applications.
Because the Chevrolet SSR (2003-2006) uses the same 194 bulb in all four side marker positions, front and rear sockets accept the same replacement unit without distinction.
The T10 wedge base of the 194 is a common fitment shared across many vehicle makes and models, though socket depth and housing retention clips can vary, making physical fit verification relevant before installation.
