Lexus ES300h Headlight Bulb Size

The Lexus ES300h uses H9 and 9005 bulb sizes for high beam headlights, while low beam headlights require H11 or D4S bulb sizes. The replacement chart covers 2013 through 2018 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.

Additional Notes

The H9 bulb, used in the Lexus ES300h high beam position for 2016-2018 with LED headlamp configurations, is a single-filament halogen type rated at 12V and 65W. It follows the ECE standard and uses a PGJ19-5 base, making it a globally recognized specification also approved for use in the United States.
The 9005 bulb serves the high beam position on 2013-2015 models and shares the same 12V, 65W electrical rating as the H9. However, it follows the ANSI standard used in the US and Canada and uses a P20d base, which differs physically from the PGJ19-5 base of the H9. These two bulbs are not interchangeable despite their identical wattage and voltage ratings.
The D4S is a mercury-free HID (xenon) discharge bulb operating at 42V and 35W, used in the low beam position on 2013-2015 models equipped with HID headlamps. It uses a P32d-5 base and is designed specifically for projector-type housings, meaning it is not suited for reflector-style headlamp assemblies.
The H11 bulb, also present in the low beam position on 2013-2015 models with halogen capsule headlamps, is a single-filament halogen type rated at 12V and 55W. It uses a PGJ19-2 base and conforms to the ECE standard while holding US approval as well.
For 2013-2015 model years, the low beam headlight position accommodates two distinct bulb types depending on the headlamp system installed. Vehicles fitted with halogen capsule headlamps use the H11, while those with HID headlamps use the D4S. These two bulb types are not interchangeable, as they differ in base type, operating voltage, and housing requirements.
The 2016-2018 high beam entries are conditioned on the presence of LED headlamps, indicating that the H9 halogen bulb functions as the high beam source within an otherwise LED-based headlamp system on the Lexus ES300h during those years.
The H9 and H11 bulbs both follow ECE standards and carry US approval, but they use different base types, PGJ19-5 and PGJ19-2 respectively, and operate at different wattages, 65W and 55W respectively. These differences make them application-specific and not substitutable for one another.
The D4S operates at 42V, a significantly higher voltage than the 12V rating of the halogen bulbs listed in these specifications. This higher operating voltage is characteristic of HID discharge technology, which requires a ballast to generate the initial high-voltage arc and sustain the discharge during operation.
