The Lexus RX330 high beam headlight uses a 9005 bulb size, while low beam headlights require either H11 or D2S bulb sizes. The replacement chart covers 2004 to 2006 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 Lexus RX330 uses three distinct bulb types across its headlight system for the 2004-2006 model years: the 9005 for high beams, and either the H11 or D2S for low beams, depending on the headlamp configuration installed at the factory.
The 9005 is an ANSI-standard single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base. It serves as the high beam bulb across all three model years covered in the specifications.
The H11 is an ECE-standard single-filament halogen bulb rated at 12V and 55W, using a PGJ19-2 base. It is the low beam bulb in RX330 units equipped with halogen capsule headlamps, and it carries approval for use in the United States despite its European origin standard.
The D2S is an HID (xenon) discharge bulb rated at 85V and 35W, using a P32d-2 base. It is designed specifically for projector-type housings and requires an external ignitor to operate, distinguishing it fundamentally from the halogen options in the same vehicle lineup.
The low beam position on the Lexus RX330 (2004-2006) accommodates two mutually exclusive bulb types. The H11 and D2S are not interchangeable, as they operate on different electrical principles, voltage levels, and physical base configurations.
The D2S operates at 85V, which is substantially higher than the 12V supply used by both halogen types. This voltage is generated internally by the HID system's ballast and ignitor assembly, meaning the bulb itself is not a direct replacement for any 12V halogen socket.
The 9005 and H11 share the same 12V operating voltage but differ in wattage, base type, and regulatory standard. The 9005 draws 65W against the H11's 55W, and their respective bases, P20d and PGJ19-2, are physically incompatible with each other's sockets.
Because the low beam fitment depends on which headlamp system the vehicle was built with, confirming whether a specific RX330 unit has halogen capsule or HID headlamps is a necessary step before selecting a replacement low beam bulb.
