Chevrolet Sprint front side marker bulb size 194 and rear side marker bulb size 168 represent the replacement specifications for this vehicle model. The replacement chart covers 1985 to 1987 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Sprint uses two distinct bulb sizes for its side marker lights across the 1985-1987 model years: the 194 for the front position and the 168 for the rear position.
Both the 194 and 168 are ANSI-standardized bulbs recognized in the United States and Canada, meaning they conform to a shared North American specification for electrical and physical tolerances.
Both bulb types share the T10 miniature wedge form factor, a small, wedge-shaped base that seats without a separate socket locking mechanism, relying instead on tension from the housing.
Although the 194 and 168 share the same T10 wedge base and the same 12-volt operating voltage, they are not interchangeable due to their differing wattage ratings.
The front side marker bulb, the 194, operates at 3.78 watts, while the rear side marker bulb, the 168, operates at 4.9 watts, making the rear unit the higher-draw bulb of the two.
The wattage difference between the 194 and 168 means that substituting one for the other could result in either an underlit marker or excess current draw relative to what the circuit was designed to handle.
The T10 wedge base shared by both bulbs is one of the most widely produced miniature bulb formats, which contributes to broad retail availability of both the 194 and 168 across automotive and general lighting suppliers.
