The Pontiac J2000 Sunbird uses a 194 bulb size for both front and rear side marker positions. The replacement chart covers 1984 to 1985 vehicle production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 194 bulb is the sole bulb type listed across all side marker positions for the Pontiac J2000 Sunbird, covering both the 1984-1985 model years.
The 194 bulb follows the ANSI standard recognized in both the United States and Canada, classifying it as a regionally standardized automotive lamp.
It is a miniature wedge-type bulb, designated T10, which refers to its tubular glass envelope and wedge base that seats directly into a socket without a separate metal base or locking pins.
The 194 operates at 12 volts, consistent with standard automotive electrical systems, and draws 3.78 watts, placing it in the low-wattage category typical of marker and courtesy lighting applications.
The same 194 bulb size is specified for both the front and rear side marker positions, indicating a single bulb type serves all four side marker locations on the vehicle.
The T10 wedge base format is a widely used fitment in automotive side marker applications, though substitution with other T10-based bulbs requires verification that voltage and wattage ratings match the original specification to avoid socket or circuit issues.
