Mazda RX-7 Headlight Bulb Size

The Mazda RX-7 high beam and low beam headlight bulbs utilize 9003, H6054, or H6024 bulb sizes depending on the specific model variant and configuration. The replacement chart covers 1979 through 1995 production years with corresponding bulb size specifications.

Additional Notes

The Mazda RX-7 uses three distinct bulb types across its production years: the 9003 halogen bulb, the H6054 rectangular sealed beam unit, and the H6024 round sealed beam unit.
The 9003 is a dual-filament halogen bulb with a P43t base, rated at 12V with a 60W high beam filament and a 55W low beam filament. A single bulb serves both high and low beam functions in the 1993-1995 RX-7.
The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V. Unlike the 9003, it is not a replaceable bulb; the entire housing unit is replaced when the light fails.
The H6024 is a 7-inch round sealed beam unit, also operating at 12V and also replaced as a complete unit rather than as an individual bulb.
All three bulb types conform to ANSI standards applicable in the United States and Canada.
The high beam and low beam positions on the Mazda RX-7 use identical bulb sizes in every model year listed, meaning a single bulb type covers both functions for any given year.
RX-7 models from 1986-1991 use the H6054 sealed beam, while those from 1979-1985 use the H6024 sealed beam. These two sealed beam types are not interchangeable due to their differing form factors.
The transition from sealed beam units to the 9003 halogen bulb in 1993 represents a shift to a replaceable-bulb design, where only the bulb itself is changed rather than the entire headlight assembly.
