The Hino FE19 front and rear turn signal bulbs utilize either 1156 or 1157 size bulbs as specified in the replacement chart. The data covers vehicle production spanning 1987 to 1992.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hino FE19 uses two distinct bulb types across its front and rear turn signal positions: the 1156 and the 1157, both governed by ANSI standards applicable in the United States and Canada.
The 1156 bulb is a single-filament type rated at 12V and 21W, fitted with a BA15s bayonet base. The single filament means it serves one lighting function only, which in this context is the turn signal.
The 1157 bulb is a dual-filament type rated at 12V with filaments drawing 21W and 5W respectively, fitted with a BAY15d bayonet base. The two filaments allow it to serve two separate lighting functions within a single housing.
The BA15s base of the 1156 and the BAY15d base of the 1157 are not interchangeable. The BAY15d base carries offset locating pins to prevent incorrect installation, while the BA15s base has symmetrical pins.
For the Hino FE19, the 1156 bulb applies to both the front and rear turn signals for model years 1989-1992.
The 1157 bulb applies to both the front and rear turn signals on the FE19 for model years 1987-1988.
The bulb specification changed between the 1988 and 1989 model years, shifting from the dual-filament 1157 to the single-filament 1156 across both front and rear turn signal positions simultaneously.
Because the 1156 and 1157 share the same 12V operating voltage and the same 21W primary filament wattage, the electrical load on the turn signal circuit differs between the two bulb types only when the secondary 5W filament of the 1157 is active.
