Toyota Land Cruiser Turn Signal Bulb Size

Additional Notes

• The 7444NA bulb is a dual-filament T20 wedge type rated at 12V with a 21W high filament and 5W low filament, featuring natural amber glass. It serves as the front turn signal on the Toyota Land Cruiser for the 2016-2021 model years.
• The "NA" suffix present on several bulb designations throughout these specifications, including the 7444NA, 7443NA, 3457NA, 1157NA, 1034NA, and 7440NA, denotes natural amber glass coloring built into the bulb envelope itself rather than achieved through an external lens or coating.
• The 1156 bulb, a single-filament BA15s bayonet base type rated at 12V and 21W, is the most consistently used bulb across the full specification range, appearing in both front and rear turn signal positions from 1975-1997 and in the front position alone from 1975-1997.
• The front and rear turn signal positions on the Land Cruiser do not always share the same bulb type within a given model year. For example, in 2013-2015 the front position uses a dual-filament T20 wedge (7443NA) while the rear uses a T15 wedge (921) or a single-filament T20 (7440NA), making the two positions non-interchangeable.
• The 3357NA, specified for the 2009 front turn signal, is the only single-filament wedge bulb in the T25 form factor listed across these specifications. It differs from the 3457NA used in 2008, 2010, and 2011, which carries a dual-filament configuration at the same 27W rating.
• The 1034 and 1034NA bulbs are described as variants of the 1157 family, sharing the BAY15d dual-filament bayonet base and a 21W/5W rating. Despite the functional similarity, the 1034NA carries the natural amber glass designation while the 1034 does not, and the two are listed under separate ANSI designations.
• The 921 bulb, a T15 wedge type rated at 12V and 16W, is specified exclusively for the rear turn signal position in 2013-2015. At 16W, it operates at a lower wattage than every other turn signal bulb listed in these specifications.
• The 2021 rear turn signal is specified as the 7440, the clear-glass variant, while the 2016-2020 rear position uses the 7440NA with natural amber glass. Both are single-filament T20 wedge bulbs rated at 12V and 21W, but the glass coloring differs between the two designations.
