The typical setup for a 2008 Pontiac G6 uses H11 bulbs for the low-beam headlights and 9005 bulbs for the high-beam headlights on halogen-equipped models. If your G6 is equipped with the factory HID option, the low beams use D2S or D3S HID bulbs with a ballast. This guide explains the common configurations and how to confirm the exact bulb in your vehicle.
Beyond this baseline, bulb types can vary by trim and production date. The following sections outline the standard halogen configuration and how to verify the specific bulb in your car.
Halogen headlight configuration (most G6s)
Before listing the common bulbs, note that the majority of 2008 G6s with halogen headlights use separate bulbs for low and high beams. The typical arrangement is shown below.
- Low-beam headlight bulb: H11
- High-beam headlight bulb: 9005 (HB5)
- Fog lights (if equipped): H11
These are the standard bulbs for most halogen-equipped Pontiac G6 models from that year. Always confirm with the bulb itself or the owner’s manual, as substitutions can occur based on trim and production date.
Factory HID headlights (optional)
For G6 models with the factory HID option, the headlight system is xenon-based rather than halogen for the low beams. The setup below reflects that configuration.
- Low-beam bulb: D2S or D3S with ballast
- High-beam bulb: If a separate high-beam is used, it is typically a halogen bulb (commonly 9005) or a HID arrangement depending on the specific headlight design; verify by checking the headlight housing label or the owner's manual
HID-equipped headlights differ from halogen units in bulb type and the need for a ballast. When in doubt, inspect the existing bulb in your headlight assembly or consult the vehicle’s documentation to confirm the exact bulb type.
How to confirm the exact bulb for your car
To ensure you purchase the correct replacement, use one of the following verification methods. This helps account for possible trim-specific variants or production changes.
- Check the owner’s manual or a factory parts diagram for your exact VIN and trim.
- Remove the headlight bulb and read the bulb’s markings, which typically show the type and wattage.
- Consult a local parts retailer or dealership with your VIN for an exact fit recommendation.
By confirming the bulb type with one of these methods, you can avoid buying the wrong replacement and ensure optimal headlight performance.
Summary
For most 2008 Pontiac G6 models, halogen headlights use H11 low beams and 9005 high beams, with H11 also commonly used for fog lights if equipped. If your G6 has factory HID headlights, the low beams use D2S or D3S bulbs with a ballast, and high-beam configurations may vary. Always verify the exact bulb type using the manual, the bulb itself, or a parts specialist to ensure a correct fit.
