Nissan Murano Turn Signal Bulb Size

Additional Notes

• The 7440NA is the most frequently specified bulb across the Nissan Murano turn signal positions, appearing in both front and rear applications across multiple model years. It is a single-filament T20 wedge bulb rated at 12V and 21W with natural amber glass, conforming to the ANSI standard for the US and Canadian markets.
• The natural amber glass construction of the NA-suffix bulbs produces an amber-colored output directly from the bulb itself, rather than relying on an amber-tinted lens. This allows these bulbs to function in clear or white lens housings while still meeting amber turn signal color requirements.
• The 7440NA and 7440 share the same T20 wedge base, voltage, and wattage rating, differing only in that the 7440NA incorporates natural amber glass. The rear turn signal positions on the 2015-2019 Murano specify the 7440NA, while earlier rear positions from 2003-2010 specify the standard 7440 without the amber coating.
• The 7443NA, specified for the front turn signal on the 2015-2018 Nissan Murano, is a dual-filament T20 wedge bulb rated at 12V with a 21W main filament and a 5W secondary filament. Although it shares the T20 wedge form with the 7440NA, its dual-filament design makes it electrically incompatible as a direct substitute for the single-filament 7440NA.
• The 2019 front turn signal position carries a production date qualifier, specifying the 2357NA for vehicles built up to November 2018. The 2357NA is a dual-filament bulb with a BAY15d bayonet base rated at 12V, 26.9W/8W, which differs in both base type and wattage from the T20 wedge bulbs used in surrounding model years.
• The BAY15d bayonet base found on the 2357NA, 1157NA, and 1034NA is physically incompatible with the T20 wedge socket used by the 7440NA and 7443NA. These two base types require different sockets, and substitution between them is not possible without a socket adapter.
• The 2010 Nissan Murano front turn signal position varies by headlamp type. Vehicles equipped with halogen capsule headlamps use the 1157NA, a dual-filament BAY15d bulb rated at 12V, 21W/5W, while those equipped with HID headlamps use the single-filament 7440NA wedge bulb.
• The 2009 Murano front turn signal similarly splits by headlamp type, with HID-equipped vehicles using the 7440NA and halogen capsule vehicles using the 1034NA. The 1034NA is described as a variant of the 1157NA, sharing the BAY15d bayonet base and a 12V, 21W/5W rating, though the two are not listed as interchangeable within these specifications.
• The 2006 rear turn signal position includes a production date qualifier, specifying the 7440 for vehicles built up to September 2005. This indicates a mid-cycle production change occurred within that model year affecting the rear turn signal fitment.
• No front turn signal entries are present for the 2003-2004, 2006-2009 (excluding the conditional 2009-2010 entries), or 2011-2014 model years, and no rear turn signal entries appear for the 2007-2008 or 2011-2014 model years within these specifications.
