The Lexus LX470 uses a 9005 bulb size for high beam headlights and an H1 bulb size for low beam headlights. The replacement chart contains specifications across 1998 to 2007 model years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Lexus LX470 uses the 9005 bulb for the high beam headlight across all model years from 1998-2007. 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 low beam headlight position on the LX470 uses the H1 bulb across the same 1998-2007 model year span. The H1 is a single-filament halogen bulb rated at 12V and 55W, governed by the ECE standard, and it uses a P14.5s base.
The 9005 and H1 bulbs are not interchangeable. Their base types differ, with the 9005 using a P20d base and the H1 using a P14.5s base, meaning each bulb is physically keyed to its respective socket and cannot be substituted for the other.
Although the H1 originates from the ECE standard used in Europe and worldwide, it also carries approval for use in the United States and Japan, which accounts for its presence in the LX470 low beam position.
The 9005 operates at 65W while the H1 operates at 55W. Both run on a 12V electrical system, consistent with standard automotive voltage, but the wattage difference means the two bulbs draw different amounts of current from the vehicle's electrical circuit.
Both the 9005 and H1 are single-filament designs, meaning each bulb serves only one lighting function. This is why the LX470 requires two distinct bulb types to cover both the high beam and low beam functions separately.
