Hino FF19 front side marker bulbs use 194 or 1156 bulb sizes, while rear side marker bulbs use 67 bulb size. The replacement chart covers 1987 to 1991 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hino FF19 front side marker uses two distinct bulb types across its model years, with the 1156 specified for 1987-1988 and the 194 specified for 1989-1991.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, conforming to ANSI standards applicable in both the United States and Canada.
The 1156 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 21W, also conforming to ANSI standards for the US and Canadian markets.
The front side marker wattage differs substantially between model year groups, as the 1156 at 21W draws considerably more power than the 194 at 3.78W.
The base type also differs between these two front side marker bulbs. The 194 uses a wedge-style base, while the 1156 uses a BA15s bayonet base, meaning the two are not interchangeable.
The Hino FF19 rear side marker is specified with the 67 bulb for 1989-1991.
The 67 bulb shares the same BA15s bayonet base and 12V rating as the 1156, but operates at a lower wattage of 8W, making it a reduced-output variant of that bulb family.
Although the 67 and 1156 share the same BA15s bayonet base type, their wattage ratings differ, and substituting one for the other would alter the electrical load on the circuit.
