The Lexus GX470 high beam headlight uses a 9005 bulb size while the low beam headlight requires an H11 bulb size. The replacement chart covers vehicle production spanning 2003 to 2009 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Lexus GX470 uses the 9005 bulb for high beam headlights across all model years from 2003-2009.
The 9005 is a single-filament halogen bulb operating at 12V and 65W, built to the ANSI standard used in the United States and Canada, and it uses a P20d base.
The H11 bulb fills the low beam headlight position on the GX470 for the full 2003-2009 production run.
The H11 is a single-filament halogen bulb rated at 12V and 55W, governed by the ECE standard, which is the regulatory framework used across Europe and much of the world, though it also carries approval for use in the United States. Its base type is PGJ19-2.
The 9005 and H11 bulbs use physically different base types, P20d and PGJ19-2 respectively, meaning the two bulbs are not interchangeable between the high and low beam sockets.
Both bulbs share the same 12V operating voltage, though the 9005 draws 65W against the H11's 55W, reflecting the higher output typically associated with high beam applications.
