Hino FD17 front side marker bulbs use 194 or 1156 size, while rear side marker bulbs use 67 size. The replacement chart covers 1988 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 FD17 front side marker uses the 194 bulb for 1989-1991, while the 1988 model year uses the 1156 bulb, indicating a change in front side marker fitment between those years.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, making it among the lowest-wattage bulbs in these specifications.
The 1156 is a single-filament bulb with a BA15s bayonet base rated at 12V and 21W, a significantly higher wattage than the 194 it was replaced by in subsequent model years.
The 67 bulb shares the same BA15s bayonet base as the 1156 but operates at 8W rather than 21W, classifying it as a lower-wattage variant of that base type.
Because the 194 uses a wedge base and the 1156 uses a BA15s bayonet base, these two bulbs are not interchangeable despite both serving the front side marker function on the Hino FD17.
The rear side marker on the Hino FD17 uses the 67 bulb across 1989-1991, and no rear side marker data is listed for 1988.
All three bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada.
The 67 and 1156 share the same BA15s bayonet base, meaning the socket form factor is physically compatible between them, though their wattage ratings differ substantially.
