The Chevrolet LUV uses 194 and 97 bulb sizes for both front and rear side marker applications. The replacement chart covers 1975 to 1982 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 LUV uses two distinct bulb types across its side marker positions: the 194 and the 97, each with different base designs and wattage ratings.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, conforming to ANSI standards for the US and Canadian markets.
The 97 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 13W, and is classified as a variant of the 1156 under ANSI standards for the US and Canadian markets.
The BA15s bayonet base of the 97 bulb is mechanically incompatible with the wedge socket used by the 194, meaning the two types are not interchangeable despite both operating at 12V.
The 97 bulb draws significantly more power than the 194, at 13W versus 3.78W, which reflects a difference in socket design and intended application between the two generations of the LUV.
The Chevrolet LUV used the 97 bulb in both front and rear side marker positions for model years 1975-1979.
Both the front and rear side marker positions transitioned to the 194 bulb for model years 1980-1982, with the same bulb type applied uniformly across both positions in those years.
The front and rear side marker positions share identical bulb specifications across all listed model years, indicating no asymmetry between front and rear fitment on the LUV.
