The 2009 Chevy Traverse uses standard halogen bulbs for its headlights: low-beam bulbs are H11, high-beam bulbs are 9005, and fog lights (if your model has them) typically use H11 as well.
Headlight bulbs by function
The following list outlines the common bulb types used for the Traverse’s headlights, high beams, and fog lights. Variations can occur by trim level or aftermarket equipment, so confirm before buying.
- Low beam (headlights): H11 halogen bulb
- High beam: 9005 (HB5) halogen bulb
- Fog lights: typically H11 (if your model has factory fog lamps)
When replacing bulbs, handle them with clean gloves or a cloth to avoid transferring oils that can shorten bulb life. If you’re upgrading to HID or LED, professional installation may be required and could necessitate different housings or wiring.
Additional considerations
Some 2009 Traverse models with optional equipment or aftermarket modifications may differ. Always verify by checking the owner’s manual or inspecting the current bulb in place to ensure you purchase the correct type.
Summary
For most 2009 Chevy Traverse models, the typical replacement bulbs are H11 for low beams, 9005 for high beams, and H11 for fog lights if equipped. Confirm with your vehicle’s documentation or a parts lookup if there is any trim-specific variation.
