Toyota Tundra high beam headlight bulbs use 9003 or 9005 sizes, while low beam headlight bulbs use 9003 or H11 sizes. The replacement bulb size chart covers 2000 to 2021 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the most frequently specified type across the Toyota Tundra headlight data. It is a dual-filament halogen bulb rated at 12V with a 60W high beam filament and a 55W low beam filament, using a P43t base. Because it carries both filaments in a single unit, it serves both high and low beam functions simultaneously in compatible housings.
The 9005 bulb is a single-filament halogen bulb rated at 12V and 65W, using a P20d base. It operates under the ANSI standard applicable in the US and Canada. Its single-filament design means it is dedicated exclusively to high beam output, which is reflected in its use only in the high beam position across the Tundra specifications.
The H11 bulb is a single-filament halogen bulb rated at 12V and 55W, using a PGJ19-2 base. It originates from the ECE standard used in Europe and worldwide but holds approval for use in the United States as well. In the Tundra specifications, it appears exclusively in the low beam position.
The Toyota Tundra (2007-2012) used a split-bulb arrangement for its headlights, with a 9005 in the high beam position and an H11 in the low beam position. These two bulbs are not interchangeable due to differing base types, wattage ratings, and regulatory standards.
For the 2013 Toyota Tundra, two distinct fitments are listed depending on production timing. Units produced from August 2013 onward used the 9003 bulb for both high and low beam positions, while earlier 2013 production used a 9005 for high beam and an H11 for low beam.
The 9003 and H11 bulbs are not interchangeable despite both being halogen and both operating at 12V. The 9003 uses a P43t base and carries dual filaments, while the H11 uses a PGJ19-2 base with a single filament. Physical and electrical differences prevent substitution between the two.
The 2019-2020 Tundra entries specify the 9003 bulb with the condition "With Halogen Capsule Headlamps," indicating that the 9003 fitment applies only to vehicles equipped with halogen-type headlamp assemblies rather than other headlamp technologies.
The Tundra used the 9003 bulb for both high and low beam positions across the 2000-2006 model years, meaning a single bulb type handled the full headlighting function in those years. The same dual-filament 9003 configuration returned for the 2018-2021 model years.
