Chevrolet Citation front and rear side marker bulbs utilize a 194 size bulb for this model. The replacement chart covers 1980 to 1983 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 Chevrolet Citation uses the 194 bulb for its front side marker position across the 1980-1983 model years.
The rear side marker position of the Citation also uses the 194 bulb across the same 1980-1983 model year span, making the front and rear side marker bulbs interchangeable with one another.
The 194 is classified as a miniature wedge bulb, designated T10 in the international bulb nomenclature system. The T10 designation refers to the tubular glass envelope, with 10 indicating its width in eighths of an inch.
The wedge base design means the 194 bulb is held in its socket by the tension of the base itself rather than by a bayonet or screw mechanism, which is a common trait in low-wattage automotive marker and interior lighting applications.
The 194 operates at 12 volts and draws 3.78 watts, placing it among the lower-wattage bulbs used in automotive lighting, consistent with its role in non-illuminating marker positions rather than primary lighting functions.
The 194 carries ANSI standardization recognized in both the United States and Canada, meaning the specification conforms to a defined performance and dimensional standard rather than being a proprietary or manufacturer-specific part number.
