Hino 185 Headlight Bulb Size

The Hino 185 uses 9003 and H6054 bulb sizes for both high beam and low beam headlight applications. Replacement specifications in the chart cover 2005 to 2010 vehicle production years.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The 9003 is a dual-filament halogen bulb, meaning a single unit contains both the high beam and low beam filaments. It operates at 12V with a 60W filament for high beam and a 55W filament for low beam, and it uses a P43t base.
The H6054 is a 5x7-inch rectangular sealed beam unit rather than a replaceable bulb. When this unit fails, the entire assembly is replaced rather than an internal filament or capsule.
Both the 9003 and H6054 are classified under ANSI standards applicable to the US and Canadian markets.
On the Hino 185, the 2006-2010 model years use the 9003 bulb for both high beam and low beam headlights.
The 2005 Hino 185 uses the H6054 sealed beam unit for both headlight positions, which represents a fundamentally different headlight construction from the 2006-2010 configuration.
Because the 9003 and H6054 are structurally incompatible, a 2005 unit is not interchangeable with any of the 2006-2010 headlight assemblies without modification to the housing.
The 9003 bulb is also commonly cross-referenced as HB2 and H4, all of which share the same P43t base and dual-filament design, though fitment should be confirmed against the original specification before substitution.
