Additional Notes

The Lexus SC300 uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across the entire 1992-2000 model range.
Both the 9005 and 9006 are ANSI-standardized halogen bulb types recognized in the United States and Canada, meaning they conform to a defined set of electrical and physical specifications.
The 9005 is a single-filament halogen bulb rated at 12V and 65W, mounted on a P20d base. Single-filament construction means the bulb serves only one lighting function, in this case high beam output.
The 9006 is a single-filament halogen bulb rated at 12V and 55W, mounted on a P22d base. Its lower wattage relative to the 9005 reflects the reduced output typical of low beam applications.
The P20d base of the 9005 and the P22d base of the 9006 are physically distinct, and the two bulb types are not interchangeable despite their similar appearance and shared halogen construction.
The consistent 9005 and 9006 fitment across all nine model years of the SC300 indicates no headlight system revision occurred during that production period.
