The Lexus LX570 high beam headlight uses a 9005 bulb size, while low beam headlight applications require D4S and H11 bulb sizes. The replacement chart covers 2008 through 2016 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9005 is an ANSI-standard halogen bulb operating at 12V and 65W with a P20d base and a single filament. It serves as the high beam bulb across the Lexus LX570 for model years 2008-2016, making it the most consistently used bulb type in these specifications.
The 2016 high beam entry carries a notation specifying halogen fitment only for units produced through September 2015, indicating a mid-cycle production change occurred within that model year.
The H11 is a single-filament halogen bulb rated at 12V and 55W with a PGJ19-2 base. It follows the ECE standard but also carries US approval, and it appears as the low beam bulb for the LX570 across model years 2008-2011.
The D4S is a mercury-free HID xenon discharge bulb rated at 42V and 35W with a P32d-5 base. Its significantly higher operating voltage compared to the halogen types in these specifications reflects the nature of high-intensity discharge technology, which requires an igniter and ballast rather than a direct 12V connection.
The D4S is designated for projector-type housings, meaning it is not interchangeable with reflector-type headlight assemblies. Its fitment on the LX570 applies to low beam positions for model years 2013-2015.
The low beam position on the LX570 transitioned from the H11 halogen type to the D4S HID type between the 2011 and 2013 model years, representing a change in both bulb technology and base type that makes the two bulbs mutually incompatible without modification.
The 9005 and H11 share the same 12V operating voltage but differ in wattage, base type, and socket design, making them non-interchangeable despite both being halogen single-filament bulbs.
The D4S follows the ECE standard, while the 9005 follows the ANSI standard used in the US and Canada. These two regulatory frameworks define different base configurations and electrical requirements, and bulbs from one standard are not compatible with sockets designed for the other.
