Pontiac Sunfire Headlight Bulb Size

The Pontiac Sunfire high beam headlight uses an H9 or 9007 bulb size, while the low beam headlight requires an H11 or 9007 bulb size. The replacement chart covers vehicle production years spanning 1995 to 2005 with corresponding bulb size specifications.

Additional Notes

The 9007 bulb is the most widely used type across the Pontiac Sunfire's headlight specifications, covering both high beam and low beam positions for the 1995-2002 model years. It follows the ANSI standard used in the US and Canada, operates at 12V, and houses two filaments within a single bulb using a PX29t base, with the high beam filament rated at 65W and the low beam filament at 55W.
Because the 9007 serves both the high beam and low beam on the 1995-2002 Sunfire, a single bulb per headlight assembly handles both lighting functions. This dual-filament design is distinct from the single-filament approach used in later model years.
For the 2003-2005 Pontiac Sunfire, the high beam and low beam positions use separate, dedicated single-filament bulbs rather than one shared dual-filament unit. The H9 handles the high beam and the H11 handles the low beam, each with its own distinct base type and wattage rating.
The H9 bulb, used in the high beam position for 2003-2005, follows the ECE standard and carries a PGJ19-5 base. It operates at 12V and 65W, matching the high beam wattage of the 9007 it replaced in that position.
The H11 bulb, used in the low beam position for 2003-2005, also follows the ECE standard and carries a PGJ19-2 base. It operates at 12V and 55W, matching the low beam wattage of the 9007 used in earlier model years.
Although the H9 and H11 share the same ECE regulatory framework and both use PGJ19-series bases, their base types are not identical. The H9 uses a PGJ19-5 base and the H11 uses a PGJ19-2 base, making the two bulbs non-interchangeable despite their similar classification.
The 9007 and the H-series bulbs used across the Sunfire's model range are not interchangeable with one another. The 9007 uses a PX29t base specific to the ANSI standard, while the H9 and H11 use PGJ19-series bases from the ECE standard, resulting in physically incompatible mounting configurations.
Both the H9 and H11 carry US approval despite originating from the ECE standard, which is primarily associated with European and worldwide markets. The 9007 originates from the ANSI standard, which is specific to the US and Canadian markets.
