Toyota Van front turn signal bulbs use 1156 or 1157 size, while rear turn signal bulbs use 1156 size. The replacement chart covers 1984 through 1989 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 1156 is a single-filament bulb operating at 12V and 21W, fitted with a BA15s bayonet base. It conforms to ANSI standards applicable in the United States and Canada.
The 1157 is a dual-filament bulb rated at 12V with two wattage outputs of 21W and 5W, fitted with a BAY15d bayonet base. It also conforms to ANSI standards for the United States and Canada.
The BA15s base of the 1156 and the BAY15d base of the 1157 are physically distinct and not interchangeable, as the offset pin arrangement of the BAY15d prevents incorrect installation in a BA15s socket.
The Toyota Van uses the 1157 for the front turn signal in 1984-1985, while the 1156 replaces it in that position for 1986-1989.
The rear turn signal on the Toyota Van uses the 1156 across all listed years, 1984-1989, without variation.
From 1986 onward, both the front and rear turn signals share the same 1156 bulb, whereas 1984-1985 models require two different bulb types depending on whether the position is front or rear.
