Chevrolet Spark Headlight Bulb Size

Additional Notes

• The 9008 bulb, used across the Chevrolet Spark for both high and low beam functions from 2013-2021, is a dual-filament halogen type operating at 12V with a 65W filament for high beam and a 55W filament for low beam, fitted with a P26t base under the ANSI standard applicable in the US and Canada.
• Because the 9008 is a dual-filament bulb, a single unit serves both the high beam and low beam circuits, which is reflected in the Chevrolet Spark specifications listing 9008 for both sub-parts across all model years covered.
• The H9 bulb is a single-filament halogen type rated at 12V and 65W, fitted with a PGJ19-5 base and governed by the ECE standard used in Europe and internationally, though it also carries US approval.
• The H9 is listed as an alternative high beam bulb size for the 2020-2021 Spark, meaning those model years accommodate either the 9008 or the H9 for the high beam position, whereas the low beam position retains only the 9008.
• The P26t base of the 9008 and the PGJ19-5 base of the H9 are physically distinct and incompatible with each other, so the two bulb types are not interchangeable despite both being halogen and sharing the same 65W high beam wattage rating.
• For the 2020 model year, the H9 high beam fitment carries an explicit exclusion for the Spark Activ Black Bumper V34 trim, indicating that variant uses only the 9008 for the high beam rather than accepting the H9 as an option.
