The typical 2015 Traverse uses H11 low-beam halogen headlights with a separate 9005 high-beam bulb; if your model has factory HID headlights, the low beams use xenon bulbs (D1S or D2S). Always confirm the exact bulb type by checking the owner’s manual or the sticker in the driver’s door jamb, since trim and options can change what your vehicle uses.
Halogen headlights (most trims)
Most 2015 Traverse models arrived with halogen headlights for the low beams and a standard high-beam bulb. This section covers the common halogen configuration you’re likely to encounter.
- Low beam: H11
- High beam: 9005 (HB3)
- Fog lights: H11 (if your model is equipped with them)
Halogen bulbs are straightforward to replace, and it’s generally advised to replace bulbs in pairs for even brightness. Use OEM or high-quality equivalents and handle bulbs with clean hands or gloves to avoid oils on the glass.
HID headlights (factory option on higher trims)
Some 2015 Traverse models were equipped with factory HID headlights. In these setups, the low-beam bulbs are xenon and require a ballast; the exact bulb type can vary by the projector design.
Low-beam xenon bulb options
- Low beam: D1S or D2S xenon bulb (depends on the specific projector/ballast configuration)
- High beam: Often a separate lighting element (may be halogen or a separate HID module); confirm with the vehicle’s documentation
Because HID assemblies involve ballast hardware and precise alignment, it’s wise to consult a dealership or qualified technician if you’re unsure about replacements or conversions.
Summary
For a 2015 Chevy Traverse, bulb type depends on the trim level and options. Halogen headlights use H11 low beams and 9005 high beams, with H11 fog lights on applicable models. If the vehicle has factory HID headlights, expect D1S or D2S xenon bulbs for the low beam and a high-beam arrangement that varies by design. To be certain, check the owner’s manual or the door jamb label and replace bulbs in matched pairs for optimal performance.
