Ford Aerostar Headlight Bulb Size

Additional Notes

• The Ford Aerostar uses two distinct headlight technologies across its production run, with the H6054 sealed beam unit fitted to 1986-1991 models and the 9007 halogen bulb fitted to 1992-1997 models.
• The 9007 is a dual-filament halogen bulb, meaning a single bulb serves both the high beam and low beam functions through two separate filaments operating at 65W and 55W respectively on a 12V system.
• The 9007 uses a PX29t base, which is a specific connector type that must be matched by any replacement bulb to ensure proper fitment in 1992-1997 Aerostar headlight assemblies.
• The H6054 is a 5x7-inch rectangular sealed beam unit, meaning the lens, reflector, and filament are fused into a single glass assembly rather than a separate replaceable bulb inside a housing.
• Because the H6054 is a sealed beam unit, the entire assembly is replaced as one piece when the light fails, rather than swapping out an individual bulb.
• Both the 9007 and H6054 are ANSI-standardized types recognized in the United States and Canada, meaning they conform to defined performance and fitment standards rather than being proprietary specifications.
• On the Ford Aerostar, the same bulb size applies to both the high beam and low beam positions for any given model year, with no separate bulb type designated for each function.
• The H6054 and 9007 are not interchangeable with each other, as one is a sealed beam unit and the other is a socket-mounted halogen bulb, requiring different headlight housing designs.
