Jeep Liberty high and low beam headlight bulbs utilize 9008 and 9007 bulb sizes across the model line. The replacement chart covers vehicle production spanning 2002 to 2012.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9007 and 9008 are the two bulb types specified for the Jeep Liberty across its full model range, and both are dual-filament halogen bulbs rated at 12V with a 65W/55W power draw, where the higher wattage serves the high beam filament and the lower wattage serves the low beam filament.
Because both the 9007 and 9008 are dual-filament bulbs, each one handles both high and low beam functions within a single housing, which is why the same bulb size appears under both the High Beam and Low Beam sub-parts in the specifications.
The 9007 and 9008 are both recognized ANSI standards applicable in the United States and Canada, meaning they conform to a defined set of electrical and photometric requirements rather than being proprietary or regional-only formats.
The primary difference between the 9007 and 9008 lies in their base type: the 9007 uses a PX29t base while the 9008 uses a P26t base. These two base types are not interchangeable, as the physical connector and pin configuration differ between them.
The Jeep Liberty (2002-2007) takes the 9007 bulb for both high and low beam headlights, while the 2008-2012 model years require the 9008 bulb for the same functions.
Despite sharing identical voltage and wattage ratings, the 9007 and 9008 cannot be substituted for one another due to their differing base designs, meaning a bulb from the 2002-2007 specification will not physically fit a 2008-2012 socket, and vice versa.
