Saturn L300 Headlight Bulb Size

Saturn L300 high beam headlight bulbs use 9005 size, while low beam headlight bulbs use H11 or 9006 size specifications. The replacement chart covers 2001 through 2005 vehicle production years with corresponding bulb size data.

Additional Notes

The Saturn L300 uses the 9005 bulb for the high beam headlight across all model years in the specifications, covering 2001-2005. It is a single-filament halogen bulb operating at 12V and 65W, fitted with a P20d base and governed by the ANSI standard used in the US and Canada.
The H11 is an ECE-standard bulb, meaning it originates from the European regulatory framework but carries US approval as well. It operates at 12V and 55W with a PGJ19-2 base, making it physically and electrically distinct from the ANSI-standard bulbs used elsewhere in the L300's headlight system.
The 9006 bulb shares the same 12V, 55W electrical rating as the H11 but uses a P22d base rather than the PGJ19-2 base of the H11. These two bulbs are not interchangeable despite their identical wattage, as the base configurations differ.
The Saturn L300 low beam headlight specification changed between the 2002 and 2003 model years. The 2001-2002 models use the 9006 bulb, while the 2003-2005 models use the H11 bulb. This base change means a bulb from one group cannot be directly substituted into a housing designed for the other.
The high beam 9005 and the low beam 9006, both ANSI-standard halogen bulbs, differ in wattage. The 9005 draws 65W while the 9006 draws 55W. They also use different bases, P20d and P22d respectively, which prevents cross-fitment between the two positions.
