Maybach 62 Turn Signal Bulb Size

Additional Notes

• The front turn signal circuit on the Maybach 62 uses two bulb types across its production run: the 1034NA and the 1157NA.
• Both the 1034NA and 1157NA are ANSI-standardized dual-filament bulbs sharing the BAY15d bayonet base and natural amber glass construction, rated at 12V with a 21W/5W filament output.
• The BAY15d base is a double-contact bayonet fitting with offset pins, a design that prevents incorrect installation by ensuring the bulb seats in only one orientation.
• The natural amber glass on both bulb types produces the amber turn signal color directly from the glass envelope rather than relying on a colored lens, which is a common requirement in North American lighting regulations.
• The 1034NA is described as a variant of the 1157NA, meaning the two share the same fundamental electrical and mechanical design with minor differences in construction or certification.
• The Maybach 62 (2005-2007, 2009-2010, 2012) specifies the 1034NA for the front turn signal position.
• The 1157NA is specified for the front turn signal on the Maybach 62 in 2003-2004, 2008, and 2011.
• Because the 1034NA and 1157NA share the same BAY15d base and identical wattage ratings, physical fitment between the two is mechanically compatible, though substitution should be confirmed against the model year specification.
