The most common setup for a 2017 Equinox is a halogen low-beam bulb of type H11 and a high-beam bulb of type 9005. Trim levels with optional or upgraded lighting may use HID or LED systems, which use different bulb configurations. Always verify with your owner’s manual or by inspecting the bulb in your vehicle.
Halogen headlights: the standard setup
If your 2017 Equinox is equipped with the traditional halogen headlights, the two primary bulbs you’ll replace are the low beams and the high beams. Below are the typical bulb types used in this configuration.
- Low-beam bulb: H11
- High-beam bulb: 9005 (HB3)
For most users, halogen replacements follow these two bulb codes. If you’re unsure, check the visor sticker, the owner’s manual, or remove the bulb to confirm the exact stamping before purchasing a replacement.
Headlights with HID technology: what changes
Some 2017 Equinox trims offered high-intensity discharge (HID) headlights. When HID is installed, the bulb type is different from halogen and is paired with a ballast. The exact bulb family depends on the projector and ballast GM chose for your vehicle.
- Low-beam HID bulb: D1S or D3S (vehicle/trim dependent)
- High-beam capability: often tied to the same HID assembly rather than a separate bulb, depending on the design
Because HID systems are highly specific to the vehicle’s optics, it’s important to confirm the exact bulb type from the manual or by consulting a GM parts specialist to avoid incorrect purchases.
LED headlights: what to know
On some higher-end trims or rare factory configurations, the Equinox may use LED headlights. In many LED setups, there isn’t a simple replace-the-bulb process like halogen bulbs. Replacements for LEDs typically involve the entire LED module or headlight assembly, and require dealer or professional service.
- LED headlights: typically not user-replaceable as a single bulb; modules or assemblies may need replacement
If your vehicle uses LEDs, verify the exact maintenance approach in the owner’s manual or with a dealer to avoid nonfunctional lights or warranty issues.
How to verify the exact bulb type for your car
Because the Equinox has had multiple lighting options across trims and production runs, confirming the precise bulb type for your specific vehicle is essential.
- Consult the owner’s manual: Headlights section usually lists the bulb types for low and high beams
- Inspect the current bulb: remove the headlight cover and read the markings on the bulb itself
- Check the driver’s door jamb or under-hood label: some GM models show recommended bulb types
- Use the VIN to look up parts: GM’s parts catalog or a dealership can confirm the exact bulb family for your build
Having the exact specification prevents buying the wrong bulb family and avoids installation delays.
Summary
For a 2017 Chevy Equinox, most models with halogen headlights use H11 for the low beams and 9005 for the high beams. If your vehicle is equipped with HID headlights, the bulbs are typically D1S or D3S and require a ballast; the high-beam behavior varies by design. LED-equipped versions generally do not use replaceable bulbs in the same way, or may require module-level replacements. To ensure accuracy, check your owner's manual, inspect the existing bulb, or consult a dealer or GM parts catalog using your VIN.
