The Chevrolet Caprice side marker requires a 194 bulb size for the lighting components located on the exterior of the vehicle. Data for the specific bulb requirements covers the range from 2011 through 2016.
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 dominant side marker specification across the Chevrolet Caprice, covering the front side marker positions for model years 1968-1990 and 2011-2017, as well as all rear side marker positions from 1968-1992.
The 194 is classified as a T10 miniature wedge bulb operating at 12 volts and 3.78 watts. Its wedge-style base requires no separate metal socket, as the glass envelope itself acts as the retention mechanism.
The 194NA specification, noted for the Chevrolet Caprice front side marker in 1968 and 1971, is a T10 miniature wedge bulb with natural amber-tinted glass. It shares the same 12-volt, 3.78-watt electrical rating as the standard 194.
Because the 194NA uses amber glass rather than a clear envelope, substituting a standard 194 in those positions would produce white light rather than amber output, which affects the color compliance of the marker lamp.
The 1991-1992 front side marker positions on the Chevrolet Caprice specify the 24 bulb, a single-filament type with a BA9s bayonet-style base. At 12 volts and 2 watts, it draws notably less power than the 194.
The BA9s base of the 24 bulb is physically incompatible with the wedge socket used by the 194. The two bulb types are not interchangeable despite both operating on a 12-volt system.
All three bulb types listed in these specifications, the 194, 194NA, and 24, conform to ANSI standards recognized in both the United States and Canada.
The rear side marker specification for the Chevrolet Caprice remains uniform at the 194 bulb across all listed model years from 1968-1992, with no variation in bulb type across that span.
The front and rear side marker positions on the 1968-1990 Caprice both use the 194 bulb, meaning the same bulb type serves both locations during those years, though the 1968 and 1971 front positions carry the amber-glass 194NA variant.
The 2011-2017 front side marker specification returns to the standard 194, consistent with the majority of earlier model years, and no rear side marker data is listed for those years in the specifications.
