Additional Notes

The 9004 is a dual-filament halogen bulb, meaning a single unit contains separate filaments for both high and low beam functions. In the Acura Integra, this design allows one bulb to serve both the high beam and low beam positions for the 1990-1993 model years.
The 9004 operates at 12 volts and draws 65 watts on the high beam filament and 45 watts on the low beam filament. It uses a P29t base, which is a specific connector type that determines physical and electrical compatibility with the socket.
The H6054 is a 5x7-inch rectangular sealed beam unit conforming to ANSI standards applicable in the United States and Canada. Unlike a replaceable bulb, the entire sealed beam assembly is the light source itself, and the whole unit is replaced when the light fails.
Because the H6054 is a sealed beam unit, it functions as both the high beam and low beam source in the 1986-1989 Integra, mirroring the dual-function role of the 9004 in later years, though through a fundamentally different construction.
Both the 9004 and H6054 are ANSI-standardized for the United States and Canadian markets, meaning their specifications are governed by a common industry standard rather than being proprietary to a single manufacturer.
The transition from the H6054 sealed beam to the 9004 halogen bulb between the 1989 and 1990 Integra represents a change in headlight architecture. These two types are not interchangeable, as they differ in base type, physical form, and installation method.
The 9004 and H6054 share the same high beam and low beam bulb size within their respective model year groups on the Integra, indicating that a single part number covers both functions per side for each generation.
