The Nissan Van front and rear turn signal bulbs both utilize a 1156 bulb size for proper illumination. The replacement chart covers 1987 to 1988 model years 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 1156 is the sole bulb type across all listed positions and model years for the Nissan Van, covering both front and rear turn signal applications for 1987-1988.
The 1156 is a single-filament bulb, meaning it performs one lighting function only, which is consistent with its use in dedicated turn signal housings rather than combined stop/turn assemblies.
The 1156 operates at 12 volts and 21 watts, a standard rating for automotive turn signal circuits of that era.
The 1156 uses a BA15s bayonet base, a single-contact bayonet mount with a 15mm collar. The "s" designation indicates a single contact pin, distinguishing it from the dual-contact BA15d base found on other bulb types.
The 1156 carries ANSI standardization applicable to the United States and Canada, indicating the specification conforms to a defined North American technical standard rather than a proprietary or regional-only format.
Because the Nissan Van uses the same 1156 bulb in both the front and rear turn signal positions, a single bulb type services all four turn signal sockets on the vehicle.
The BA15s base of the 1156 is not interchangeable with visually similar bulbs that use a BA15d base, such as the 1157, despite sharing the same 15mm bayonet collar width. Substituting a dual-contact base bulb into a single-contact socket is not possible without modification.
