Additional Notes

The Toyota 4Runner uses three distinct daytime running light bulb types across its model years: the 9005, 1156NA, and 4157NA.
The 9005 is a single-filament halogen bulb operating at 12V and 65W, fitted with a P20d base. It is the specified daytime running light bulb for the 2014-2022 4Runner.
The 1156NA is a single-filament bulb rated at 12V and 21W, using a BA15s bayonet base. Its natural amber glass distinguishes it visually from clear-glass equivalents. It is specified for the 2010-2013 4Runner.
The 4157NA is a dual-filament bulb in a T25 wedge form, rated at 12V with a 27W high filament and a 7W low filament. Its natural amber glass is part of the ANSI designation. It is specified for the 2006-2009 4Runner.
For the 2003-2005 Toyota 4Runner, the 4157NA fitment applies only to vehicles equipped with the daytime running lamp option, indicating that not all units of those model years carried this system as standard equipment.
The 9005 and 1156NA are both single-filament designs, but they are not interchangeable. The 9005 uses a P20d base and draws 65W, while the 1156NA uses a BA15s bayonet base and draws only 21W, making the two physically and electrically incompatible.
The 4157NA's dual-filament construction sets it apart from the other two bulb types in these specifications. A dual-filament bulb contains two separate tungsten filaments within one envelope, allowing it to serve two distinct brightness levels from a single housing.
All three bulb types conform to ANSI standards recognized in both the United States and Canada, placing them within a standardized North American automotive lighting classification system.
