Hino FD2218LP front and rear side marker bulbs use 194 and 67 sizes respectively. The replacement chart covers 1993 to 1995 production years with bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hino FD2218LP uses two distinct bulb types for side marker functions across the 1993-1995 model years: the 194 for front positions and the 67 for rear positions.
The 194 is an ANSI-standardized miniature wedge bulb of the T10 form factor, rated at 12V and 3.78W, making it one of the lower-wattage bulbs in common automotive use.
The T10 wedge base of the 194 bulb requires no locking mechanism for retention; the wedge shape itself holds the bulb within the socket, which is a defining characteristic of this base type.
The 67 bulb is an ANSI-standardized single-filament type with a BA15s bayonet base, rated at 12V and 8W, and is classified as a lower-wattage variant of the 1156 bulb family.
The BA15s designation on the 67 bulb indicates a single-contact bayonet base with a 15mm collar, which is not interchangeable with the BA15d double-contact variant used in dual-filament applications.
Because the 194 and 67 bulbs use fundamentally different base types, a wedge socket and a bayonet socket respectively, the front and rear side marker positions on the FD2218LP are not interchangeable with each other.
Both the 194 and 67 carry ANSI standardization applicable to the US and Canadian markets, meaning their electrical and physical specifications conform to a defined industry standard rather than a proprietary format.
The wattage difference between the front 194 at 3.78W and the rear 67 at 8W reflects a more than twofold increase in power consumption at the rear side marker positions relative to the front.
