Hino FB14 front and rear side marker bulbs utilize 194 and P21W sizes for front applications and 67 size for rear positions. The replacement chart covers 1987 to 1991 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hino FB14 front side marker uses two distinct bulb types across its model years: the 194 for 1989-1991 and the P21W for 1987-1988.
The 194 is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12V and 3.78W, and is common in North American automotive applications.
The P21W follows the ECE standard used in European and international markets, features a BA15s single-contact bayonet base, and is rated at 12V and 21W, making it significantly higher in wattage than the 194 it replaced in later FB14 model years.
Because the 194 uses a wedge base and the P21W uses a BA15s bayonet base, the two bulb types are not interchangeable despite both serving the front side marker function on the Hino FB14.
The rear side marker on the Hino FB14 uses the 67 bulb for 1989-1991.
The 67 is an ANSI-standard single-filament bulb with a BA15s bayonet base, rated at 12V and 8W.
Although the 67 and the P21W share the same BA15s bayonet base type, their wattage ratings differ substantially, at 8W and 21W respectively, which affects their suitability for specific socket and circuit applications.
The 67 bulb is described as a lower-wattage variant of the 1156, meaning the two share a base type but are not rated identically and are not direct substitutes in all applications.
