The Jeep Commander high beam headlight uses a 9005 bulb size while low beam headlights require either 9006 or D1S bulb sizes. Replacement specifications in the chart cover 2006 through 2010 vehicle production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9005 bulb serves as the high beam headlight across all Jeep Commander model years covered in the specifications, spanning 2006-2010. It is an ANSI-standard single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base.
The 9006 bulb is the low beam headlight for the 2006-2008 Commander and remains one of two low beam options for 2009-2010. It is an ANSI-standard single-filament halogen bulb rated at 12V and 55W, using a P22d base.
Although the 9005 and 9006 share the same ANSI halogen family and voltage rating, they are not interchangeable. The 9005 draws 65W against the 9006's 55W, and their base types differ, with the P20d on the 9005 and the P22d on the 9006.
For 2009-2010 Commander models equipped with HID headlamps, the low beam position uses the D1S bulb rather than the 9006. The D1S is an ECE-standard high-intensity discharge xenon bulb rated at 85V and 35W, with a PK32d-2 base and an integral ignitor built into the bulb body.
The D1S operates on a fundamentally different electrical principle than the halogen 9006. It produces light through a xenon gas discharge arc rather than a heated tungsten filament, which accounts for its substantially higher operating voltage of 85V.
The D1S is specified for projector-type housings, meaning it is not a drop-in replacement for the reflector-style housings associated with halogen low beam configurations on the same vehicle.
The presence of an integral ignitor on the D1S distinguishes it from some other HID bulb types that rely on a separate external ignitor module, making the D1S a self-contained discharge unit.
The halogen bulbs in these specifications, the 9005 and 9006, conform to ANSI standards applicable in the United States and Canada, while the D1S conforms to ECE standards used in Europe and other markets worldwide.
