Volvo ACL high beam and low beam headlight bulbs use 9004 or H6024 size specifications. The replacement chart covers vehicle production years from 1996 to 1997 with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volvo ACL covers the 1996-1997 model years in these headlight bulb specifications, with both years sharing identical bulb fitment across high beam and low beam positions.
Two distinct headlamp system types are listed for the Volvo ACL: halogen capsule headlamps and sealed beam headlamps. These represent fundamentally different headlamp technologies, and the correct bulb size depends entirely on which system is installed on the vehicle.
The 9004 is a dual-filament halogen bulb, meaning a single bulb serves both the high beam and low beam functions within a halogen capsule headlamp system. It operates at 12V with a 65W output for high beam and 45W for low beam, and uses a P29t base.
The 9004 bulb conforms to ANSI standards applicable in the United States and Canada, which governs its electrical and photometric performance requirements.
The H6024 is a 7-inch round sealed beam unit that also serves both the high beam and low beam positions in the sealed beam headlamp system. Unlike the 9004, the H6024 is not a replaceable bulb; the entire sealed unit is replaced when the light source fails.
The H6024 also conforms to ANSI standards for the US and Canadian markets and operates at 12V, though no wattage breakdown by beam function is specified in its description.
Because the 9004 and H6024 are associated with two separate and incompatible headlamp system types, the two bulb sizes are not interchangeable with one another regardless of beam position.
