The Hino FF3020 front and rear turn signal bulbs both utilize a 1156 size bulb for proper operation. The replacement chart covers vehicle production spanning 1993 to 1995.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1156 is the sole bulb type listed across all turn signal positions for the Hino FF3020, covering model years 1993-1995.
The 1156 is a single-filament bulb, meaning it serves one lighting function per socket rather than combining two functions such as braking and signaling into a shared unit.
It operates on a 12-volt electrical system and draws 21 watts, which places it within the standard range for automotive turn signal applications.
The 1156 uses a BA15s bayonet base, a single-contact fitting where the "s" designation indicates a single pin, distinguishing it from the dual-contact BA15d variant.
The 1156 carries ANSI standardization applicable in both the United States and Canada, reflecting a common specification across North American automotive markets.
Both the front and rear turn signal positions on the Hino FF3020 share the same 1156 specification across all listed model years, indicating socket compatibility between the two positions.
Because the BA15s base has a single contact pin, substituting a dual-contact bayonet bulb such as the 1157 would result in an incompatible fit despite the physical similarity of the base housing.
