The Mazda 808 front and rear turn signal bulbs both utilize a 1157 bulb size for proper operation. The replacement chart covers vehicle production spanning 1972 to 1977 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 Mazda 808 uses the 1157 bulb for both the front and rear turn signals across the full 1972-1977 production run.
The 1157 is a dual-filament bulb, meaning it contains two separate filaments within a single glass envelope, allowing it to serve two distinct lighting functions at different wattages.
The 1157 operates at 12 volts and draws 21 watts on its high-intensity filament and 5 watts on its low-intensity filament.
The 1157 uses a BAY15d bayonet base, which is an offset twin-pin mount. The two pins are positioned at different heights, making directional insertion necessary and preventing incorrect installation.
The 1157 conforms to ANSI standards and is recognized across the United States and Canada, placing it within a widely distributed North American bulb classification system.
Because the front and rear turn signal positions on the Mazda 808 share the same 1157 specification, a single bulb type serves all four turn signal sockets on the vehicle.
The BAY15d base of the 1157 is not interchangeable with the BAY15s single-pin bayonet base used by single-filament bulbs such as the 1156, despite the physical housing appearing similar in size.
