Chevrolet Captiva Sport high beam headlight bulb size is H9 and low beam headlight bulb size is H11. The replacement chart covers 2012 to 2015 model years with bulb specifications for each production year.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Captiva Sport uses the H9 bulb for high beam headlights and the H11 bulb for low beam headlights across the 2012-2015 model years.
The H9 is a single-filament halogen bulb operating at 12V and 65W, built to the ECE standard used in Europe and worldwide, and also approved for use in the United States.
The H11 is a single-filament halogen bulb operating at 12V and 55W, likewise conforming to the ECE standard and carrying US approval.
The H9 uses a PGJ19-5 base, while the H11 uses a PGJ19-2 base. Although both belong to the PGJ19 base family, the differing pin configurations make the two bulbs physically non-interchangeable between the high and low beam sockets.
The 10W power difference between the H9 (65W) and the H11 (55W) reflects their respective roles, as high beam circuits typically draw more wattage to produce the greater light output required for long-range illumination.
Single-filament construction in both bulb types means each serves only one lighting function, which is why the Captiva Sport requires separate bulbs for high and low beam operation rather than a dual-filament unit.
