The INFINITI QX30 high beam and low beam headlight bulbs both utilize an H9 size. The replacement chart covers 2017 to 2019 model years 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 INFINITI QX30 uses the H9 bulb for both high beam and low beam headlights across the 2017-2019 model years, applicable only to vehicles equipped with halogen capsule headlamps.
The H9 is an ECE-standard single-filament halogen bulb operating at 12 volts and 65 watts, fitted with a PGJ19-5 base, and carries approval for use in both European and US markets.
Because both the high beam and low beam positions share the H9 specification on the QX30, the same bulb type serves dual functions within the headlamp assembly, though each position remains a separate physical installation.
The halogen capsule headlamp condition attached to every model year entry indicates that the H9 fitment applies exclusively to that headlamp configuration, meaning vehicles with a different headlamp system would fall outside this specification.
The PGJ19-5 base is specific to the H9 and is not shared with closely related bulbs such as the H8 or H11, which use the PGJ19-1 and PGJ19-2 bases respectively, making those types physically incompatible despite similar appearances.
At 65 watts, the H9 produces a higher output than the H11, which is rated at 55 watts, a distinction relevant when considering any cross-reference or substitution between these ECE-family bulbs.
