The DeLorean DMC 12 front and rear side marker bulbs both utilize a 3893 bulb size. The replacement chart covers vehicle production spanning 1981 to 1983.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 3893 bulb is the sole bulb type specified across all side marker positions on the DeLorean DMC 12, covering both front and rear locations for the 1981-1983 model years.
The 3893 is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, allowing it to serve more than one lighting function from a single housing.
The 3893 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of that era.
The 3893 uses a BAY15d bayonet base, a two-pin offset base type where the two pins are positioned at different heights to ensure the bulb can only be seated in one rotational orientation, preventing incorrect filament alignment.
The BAY15d base is classified as a specialty application fitting, distinguishing it from more common single-pin bayonet bases used in general automotive lighting.
The 3893 carries ANSI standardization applicable in both the United States and Canada, meaning its physical and electrical characteristics conform to a defined North American specification.
Because the front and rear side marker positions on the DeLorean DMC 12 share the same 3893 bulb type, the front and rear sockets accept the same physical fitment, though the dual-filament nature of the bulb means wiring configuration at each position may differ.
