Oldsmobile Omega headlight bulbs utilize H6054 and H6024 sizes for both high and low beam applications, with bulb specifications varying across the model line. The replacement chart covers 1973 to 1984 production years and details the corresponding bulb size requirements for each generation.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6054 and H6024 are the two sealed beam types specified for the Oldsmobile Omega across its full model range. Both conform to ANSI standards recognized in the United States and Canada and operate on a 12-volt electrical system.
The H6054 is a 5x7-inch rectangular sealed beam unit. Because the lens, reflector, and filament are fused into a single assembly, the entire unit is replaced rather than an internal bulb.
The H6024 is a 7-inch round sealed beam unit and shares the same sealed construction as the H6054, meaning the whole assembly is replaced when the unit fails.
For the Oldsmobile Omega, the H6054 applies to both high beam and low beam headlights for the 1980-1984 model years. A single sealed beam type therefore serves both functions in those years.
The H6024 applies to both high beam and low beam headlights for the 1973-1979 model years, again with one sealed beam type covering both functions.
The rectangular H6054 and the round H6024 are not interchangeable. Their housing shapes differ, and each requires a matching mounting bucket in the vehicle body.
The transition from H6024 to H6054 occurred between the 1979 and 1980 model years, representing a change in headlight housing geometry that affects physical fitment.
Because both the H6054 and H6024 are ANSI-standardized sealed beam units, replacement assemblies from any manufacturer conforming to the same ANSI designation are dimensionally equivalent to the original equipment.
