Maybach 57 Turn Signal Bulb Size

The Maybach 57 front turn signal bulb utilizes either 1157NA or 1034NA size bulbs for proper illumination. A replacement chart covering 2003 to 2012 model years documents the bulb specifications across the vehicle's production span.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The front turn signal positions across the Maybach 57 (2003-2012) use one of two bulb types: the 1157NA or the 1034NA, both of which are ANSI-standardized dual-filament bulbs rated at 12V with a 21W/5W output configuration.
Both the 1157NA and 1034NA share the BAY15d bayonet base, a two-pin offset base design that physically locks the bulb into the socket at a fixed rotational position to align the dual filaments correctly.
Both bulb types feature natural amber glass, meaning the amber color is produced by the glass itself rather than by a coating applied over clear glass.
The 1034NA is classified as a variant of the 1157, and while the two types share the same base type and voltage-wattage rating, they are not the same part number and are not listed as interchangeable within these specifications.
The Maybach 57 (2004, 2007-2008, 2011-2012) uses the 1157NA for the front turn signal, while the 2003, 2005-2006, 2009-2010 model years use the 1034NA instead.
The front turn signal bulb specification on the Maybach 57 alternates between the 1157NA and 1034NA across different model years, meaning the same socket position does not consistently accept the same part number throughout the production run.
The dual-filament design of both bulb types allows a single bulb to serve two separate lighting functions, with the higher 21W filament typically assigned to the turn signal function and the lower 5W filament to a secondary function such as parking or running light duty.
