The 2010 Pontiac G6 primarily uses standard halogen headlights: low beams are typically H11, high beams are usually 9005, and fog lights (where equipped) commonly use H3. Some trims offered optional HID headlights, which use a ballast-based system rather than replaceable halogen bulbs.
The G6 lineup from that year featured multiple trims and regional options, so bulb choices can vary by market and package. This article explains the typical configuration and how to verify your exact setup.
Bulb types by function
Below is a straightforward guide to the common headlight bulb configurations you may encounter on a 2010 G6. Before relying on one of these, confirm with your vehicle’s manual or by inspecting the bulb itself, since variations exist by trim and region.
- Low beam headlights: usually H11 halogen bulbs (standard for most trims).
- High beam headlights: usually 9005 (HB3) bulbs (standard for most trims).
- Fog lights: commonly H3 bulbs, when the car is equipped with fog lamps.
- Optional HID headlights: on some trims or markets, the G6 may use HID assemblies with ballast and bulbs (D1S/D2S style depending on the system).
Because bulb configurations can vary by market and option package, always verify by checking the bulb currently installed, consulting the owner’s manual, or referencing an official parts diagram for your VIN.
Why the exact bulb matters
Using the correct bulb type ensures optimal light output, proper beam pattern, and electrical compatibility. If you’re replacing bulbs yourself, bring the old bulb to the parts counter or check the service manual to confirm the exact specification for your vehicle’s trim and region.
Summary
In most cases, a 2010 Pontiac G6 uses H11 low beams, 9005 high beams, and H3 for fog lights; some factory or dealer-installed HID options may use ballast-based bulbs. Always verify with the owner's manual or by inspecting the installed bulb to ensure you choose the correct replacement for your specific vehicle.
