Mercedes-Benz 600 front and rear side marker bulbs use a 3893 bulb size. The replacement chart covers 1964 to 1972 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 Mercedes-Benz 600 uses the 3893 bulb for both front and rear side marker positions across the 1964-1972 model years.
The 3893 is an ANSI-standardized bulb type, meaning its physical and electrical characteristics conform to a defined North American specification recognized in both the United States and Canada.
The 3893 bulb operates on a 12-volt electrical system, consistent with the standard automotive voltage architecture used in passenger vehicles of this era.
As a dual-filament bulb, the 3893 contains two separate filaments within a single envelope, allowing it to serve more than one lighting function from a single socket.
The 3893 uses a BAY15d bayonet base, which is an offset twin-pin mount. The offset pin arrangement is a deliberate anti-misalignment feature, ensuring the bulb can only be seated in one rotational orientation within its socket.
The BAY15d base type is directly associated with the dual-filament design, as the two offset pins correspond to the two separate electrical contacts required to power each filament independently.
The 3893 is classified as a specialty application bulb, indicating it is not among the most broadly distributed automotive bulb types and may have a more limited retail availability compared to high-volume standard bulbs.
Because the same 3893 bulb size is specified for both the front and rear side marker positions on the Mercedes-Benz 600, the two positions share full bulb interchangeability with each other across all listed model years.
