The typical halogen setup for most 2007 Pontiac G6 models uses H11 for the low beams and 9005 for the high beams. If your G6 has factory HID headlights, it will use HID bulbs instead of halogen ones, which are not interchangeable with H11 or 9005.
Halogen configuration (most models)
The following bulbs cover the standard, non-HID headlight setup commonly found on 2007 G6s. This is the configuration most owners will encounter when replacing bulbs.
- Low beam: H11
- High beam: 9005
In this halogen arrangement, the low and high beams use separate bulbs, so you’ll replace each one accordingly. Always verify by inspecting the current bulb or checking the owner's manual for your specific trim and production date when replacing.
High-intensity discharge (HID) configuration
A subset of 2007 G6s were equipped with factory HID headlights. If your vehicle has HID, you won’t use halogen bulbs (H11/9005). HID systems rely on ballast-stabilized bulbs, and the exact bulb type can vary by assembly.
- Common HID bulb types (dependent on the headlamp assembly): D2S/D2R or D3S
Because HID systems differ from halogen ones, replace HID bulbs only with the correct type specified for your exact headlamp unit and VIN. If you’re uncertain, consult the vehicle’s manual or a qualified technician.
How to verify and replace safely
To ensure you get the right bulb, remove and inspect the current bulb for markings, check the headlamp housing for part numbers, or consult the owner’s manual. If you’re unsure, bring the original bulb to an auto parts store or contact a dealer with your VIN to confirm the exact specification.
Summary
For most 2007 Pontiac G6 models with halogen headlights, use H11 for low beams and 9005 for high beams. If your G6 has factory HID headlights, you will need the appropriate HID bulbs (such as D2S/D2R or D3S, depending on the assembly) and a ballast. Always verify the exact bulb type for your trim and production date to ensure proper fit and performance.
