The Hino FF3018 uses a 194 bulb size for front side marker applications and a 67 bulb size for rear side marker positions. The replacement chart covers 1993 to 1995 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 FF3018 uses two distinct bulb types across its side marker positions for the 1993-1995 model years: the 194 at the front and the 67 at the rear.
The 194 is an ANSI-standard miniature wedge bulb in the T10 form factor, rated at 12V and 3.78W, and is among the most widely used low-wattage marker bulbs in North American vehicle applications.
The T10 wedge base of the 194 requires no locking mechanism, as the bulb is held in place by the tension of the socket itself, which is a common trait of miniature wedge designs.
The 67 is an ANSI-standard single-filament bulb fitted with a BA15s bayonet base, rated at 12V and 8W, making it notably higher in wattage than the front marker bulb used on the same vehicle.
The BA15s designation on the 67 indicates a single-contact bayonet base with a 15mm collar, which is not interchangeable with dual-contact bayonet bases such as BA15d.
The 67 is described as a lower wattage variant of the 1156, meaning both share the BA15s bayonet base but differ in wattage output, so substituting a 1156 in place of a 67 would result in higher power draw than the original specification.
Both the 194 and 67 conform to ANSI standards applicable in the United States and Canada, reflecting their suitability for North American market vehicles.
The front and rear side marker positions on the Hino FF3018 use physically incompatible bulb bases, as the 194 uses a wedge-style socket and the 67 uses a bayonet-style socket, making cross-position substitution impossible without socket modification.
