Hino 258LP high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 2006 to 2014.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hino 258LP uses the 9003 bulb for both high beam and low beam headlights across all model years from 2006 to 2014.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
Because both filaments are housed in one bulb, the 9003 serves the high beam and low beam functions simultaneously, which is why the same bulb size appears in both headlight positions on the 258LP.
The 9003 operates on a 12-volt electrical system and uses a P43t base, which is a bayonet-style fitting with a 43mm collar width.
The 9003 designation follows the ANSI standard used in the United States and Canada, distinguishing it from the functionally similar H4 bulb used under European ECE standards, which shares the same dual-filament halogen design but carries a different designation.
The P43t base of the 9003 and the P43t base of the H4 are physically similar, but the two bulb types are not considered interchangeable due to differences in filament positioning that affect beam pattern alignment.
