Additional Notes

The Toyota Land Cruiser backup light specifications cover three distinct bulb types across the full model range: the 921 (T15 wedge), the 7440 (T20 wedge), and the 1156 (BA15s bayonet). The 921 is the most widely specified, appearing across the greatest number of model years in both the standard and inner backup light positions.
The 921 is a T15 wedge bulb rated at 12V and 16W. It draws less wattage than the 7440 and 1156, both of which are rated at 21W, making the 921 a lower-power single-filament wedge type.
The 7440 is a T20 single-filament wedge bulb rated at 12V and 21W. The 1156 is also a single-filament 12V, 21W bulb but uses a BA15s bayonet base rather than a wedge-style connector, making the two physically incompatible despite sharing the same voltage and wattage ratings.
The 1003 bulb, specified for the Toyota Land Cruiser from 1969-1974, also uses a BA15s bayonet base and is rated at 12V and 21W, placing it in the same electrical class as the 1156. However, the 1003 and 1156 are separate ANSI designations and are not listed as interchangeable in these specifications.
The inner backup light position on the Toyota Land Cruiser shows a production-date-specific fitment for certain years. The 2008 model year uses the 921 only from 09/2007 onward, while the 2005 model year uses the 3057 from 05/2005 onward, and the 2002 model year uses the 7440 from 08/2002 onward. Vehicles produced before those cutoff dates within the same model year require a different bulb.
The 3057 is a dual-filament T25 wedge bulb rated at 12V with a 27W high filament and a 7W low filament. Its dual-filament design distinguishes it from all other bulb types in these specifications, which are all single-filament units. It appears only in the inner backup light position for the 2005 and 2007 model years.
The outer backup light sub-part is specified only for the 1995-1997 Toyota Land Cruiser, with the 1156 bulb listed for all three years in that position.
All five bulb types in these specifications conform to ANSI standards applicable in both the United States and Canada, and all operate on a 12V electrical system.
