The 9005 is an ANSI-standardized single-filament halogen bulb used across North American markets. It operates at 12 volts and 65 watts, and is fitted with a P20d base, which is a push-and-turn locking connector type common in automotive high beam applications.
The Lexus NX300h uses the 9005 bulb for the high beam headlight across the 2015-2018 model years, though this fitment applies specifically to vehicles equipped with halogen capsule headlamps.
The halogen capsule headlamp designation is a critical compatibility condition. NX300h vehicles not equipped with this headlamp configuration are not covered by these specifications, meaning the 9005 fitment does not apply universally across all NX300h headlamp variants.
