The Hino FD2218 front turn signal bulb uses a P21W size while the rear turn signal bulb uses a 1156 size. The replacement chart covers vehicle production spanning 1993 to 1995 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 FD2218 uses two distinct turn signal bulb types across its front and rear positions, with the front requiring P21W bulbs and the rear requiring 1156 bulbs for the 1993-1995 model years.
The P21W is governed by ECE standards, which are used in Europe and internationally, while the 1156 follows ANSI standards, which apply in the United States and Canada.
Despite originating from different standardization bodies, both the P21W and 1156 share identical electrical ratings of 12 volts and 21 watts, as well as a BA15s bayonet base.
The BA15s designation refers to a single-contact bayonet base with a 15mm collar, which is a common base type for single-filament automotive signal bulbs.
Both bulb types are single-filament designs, meaning each serves a dedicated function rather than combining multiple lighting operations such as braking and signalling into one unit.
Although the P21W and 1156 are electrically and physically similar due to their shared base type and ratings, their differing regulatory standards mean they are not guaranteed to be interchangeable in all applications without verification.
