The Pontiac J2000 front and rear side marker bulbs both require a 194 size bulb for proper operation. The replacement chart covers 1982 to 1983 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 Pontiac J2000 uses the 194 bulb across both front and rear side marker positions for the 1982-1983 model years.
The 194 is classified as a miniature wedge bulb, designated T10 in the international bulb sizing system, where "T" refers to a tubular shape and "10" indicates the width in eighths of an inch.
The 194 bulb operates at 12 volts with a power draw of 3.78 watts, placing it in the low-wattage range typical of marker and courtesy lighting applications.
The wedge base design of the 194 means the bulb is held in its socket by the tension of the base itself rather than by a separate metal bayonet or screw fitting, which is a common trait in side marker applications of this era.
The 194 carries ANSI standardization recognized in both the United States and Canada, meaning the bulb conforms to a defined set of electrical and physical tolerances shared across manufacturers.
Because the same 194 bulb size is specified for all four side marker positions on the J2000, front and rear sockets accept the same replacement bulb without substitution.
