The Lexus LS460 high beam headlight uses a D4S bulb size, while the low beam headlight requires a D4S bulb size as well. The replacement chart covers vehicle production spanning 2007 to 2017 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 D4S bulb type is the most consistently specified across the Lexus LS460 headlight system, appearing in low beam positions across all model years from 2007-2017 and in high beam positions from 2013-2017 on HID-equipped vehicles. It operates at 42V and 35W, uses a P32d-5 base, and functions as a mercury-free high-intensity discharge (xenon) unit designed specifically for projector-type housings.
The 9005 bulb follows the ANSI standard used in the United States and Canada. It is a single-filament halogen type with a P20d base, rated at 12V and 65W. On the Lexus LS460, it serves the high beam position across all years from 2007-2017, either as the sole high beam bulb or as the halogen alternative on non-HID trims.
The D4S conforms to ECE standards, which govern lighting equipment across Europe and many international markets. Its P32d-5 base is not interchangeable with the P20d base of the 9005, meaning the two bulb types are physically incompatible and cannot be substituted for one another regardless of wattage or voltage differences.
For the Lexus LS460 high beam circuit in model years 2013-2017, two distinct bulb sizes are listed: D4S for vehicles equipped with HID headlamps and 9005 for those with halogen headlamps. Selecting the correct replacement requires confirming which headlamp system is installed on the specific vehicle.
The low beam circuit of the Lexus LS460 uses the D4S exclusively across all listed model years from 2007-2017, with no halogen alternative specified for any year in that position.
The high beam circuit for model years 2007-2012 lists only the 9005 halogen bulb, with no HID variant noted for those years in that position. From 2013 onward, the HID D4S option is added alongside the 9005 for the high beam.
The voltage difference between the D4S (42V) and the 9005 (12V) reflects fundamentally different operating systems. HID bulbs require a ballast to generate the high-voltage arc needed for ignition, while halogen bulbs operate directly on the vehicle's standard 12V electrical system.
Because the D4S is mercury-free, it falls within environmental compliance standards that restrict mercury content in automotive lighting components, a distinction relevant to disposal regulations in markets where such rules apply.
