The Buick Verano high beam headlight uses an H9 bulb size while the low beam headlight requires an H11 bulb size. Replacement specifications within the chart cover 2012 through 2017 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Buick Verano uses the H9 bulb for the high beam headlight across all model years from 2012-2017.
The H9 is a halogen bulb operating at 65 watts with a PGJ19-5 base. It produces a high-intensity output suited for high beam applications.
The H11 bulb fills the low beam headlight position in the Verano for the full 2012-2017 production run.
The H11 is a single-filament halogen bulb rated at 55 watts with a PGJ19-2 base, designed for sustained low beam use.
Although the H9 and H11 share the same PGJ19 base family and physically similar housings, they are not interchangeable. The H9 has a different filament position and wattage rating than the H11, and substituting one for the other risks improper light projection and potential socket damage.
The consistent use of H9 and H11 across all six model years of the Verano means that replacement bulbs sourced for any year within the 2012-2017 range will fit any other year within that same range for their respective positions.
