The 2017 Chevy Traverse primarily uses halogen bulbs for the headlights: low beams use H11, high beams use 9005, and fog lights use H11. Some trims offered factory HID headlights, which use different bulb types (D1S or D3S). Always verify the exact type for your vehicle by checking the owner's manual or the headlight housing label.
Standard halogen configuration
If your Traverse uses standard halogen headlights, use the following sizes:
- Low beam: H11
- High beam: 9005 (HB3)
- Fog lights: H11
These sizes cover the typical halogen setup on the 2017 Traverse. Trim and regional variations may alter the exact bulb type, so confirm before purchasing replacements.
Optional HID headlight configuration
If your vehicle is equipped with factory HID headlights, the bulb type is different from halogen systems and is not a direct halogen replacement.
- Bulb types: typically D1S or D3S for HID headlights (verify on your specific vehicle by checking the ballast label or owner's manual).
Note: HID systems require ballast components and are not interchangeable with halogen bulbs. If uncertain, consult a dealer or a qualified automotive technician.
How to identify and replace bulbs
Use these steps to confirm your bulb type and perform a replacement safely.
- Park on a level surface and turn off the engine; engage the parking brake.
- Open the hood and locate the headlight assembly; remove the dust cap from the rear of the headlight (for halogen) or ballast cover (for HID).
- Disconnect the electrical connector, release any retaining clip or ring, and remove the old bulb from the housing.
- Install the new bulb of the same type, reattach connectors and caps, and test the headlight before closing the hood.
- If replacing HID bulbs, you may need to handle the ballast and ensure proper alignment of the HID kit; consider professional service if unsure.
Always ensure you buy the exact bulb type specified for your trim and year, and follow all safety precautions when handling hot bulbs or high-voltage HID components.
Summary
In summary, the 2017 Chevy Traverse mostly uses halogen headlights with H11 low beams, 9005 high beams, and H11 fog lights. Some trims with factory HID headlights use D1S or D3S bulbs. Confirm the exact configuration by checking the owner's manual or the headlight housing labels, and replace bulbs with the proper type.
