The correct bulb depends on the model year and the headlight type (halogen, HID, or LED). There isn’t a single bulb size that fits every Equinox.
To determine the exact bulb number for your specific vehicle, identify your year and trim, consult the owner’s manual or a GM parts diagram, and verify the size printed on the existing bulb or in the headlight housing. If you share your year and trim, I can give you the precise bulb size and cross-reference.
To help you determine the exact bulb, follow these steps:
- Identify the exact year and trim of your Equinox. This determines the headlight configuration and compatible bulbs.
- Confirm the headlight technology on your model (halogen, HID, or LED). LED headlights on some trims are not simple bulb replacements and may require modules or assemblies.
- Consult the owner’s manual or a GM parts diagram for the precise bulb size used by your year/trim.
- If you can access the current bulb, read the base type or size printed on the bulb itself or on the packaging to confirm compatibility.
- If you can’t locate the manual, use an online bulb finder by entering year, make, model, and trim to identify the correct sizes.
- Order the exact size and install with care. If both sides show wear, consider replacing in pairs and follow proper safety steps to avoid damaging wiring or seals.
Using these steps will help ensure you select the correct bulb for your Equinox and avoid buying the wrong size.
Common headlight configurations by generation
These patterns reflect what many Chevrolet Equinox models have used in recent years, but configurations can vary by trim and market. Always verify against your manual or GM’s official parts lookup for your exact vehicle.
- First generation (2005–2009): Halogen low beams and high beams are typical; fog lights often use H11.
- Second generation (2010–2017): Similar halogen setup for low/high beams; fog lights commonly use H11; verify per trim.
- Third generation (2018–present): Some trims offer LED headlights (not all), which may not use a simple replaceable bulb for the main headlight. Halogen variants in lower trims typically use H11 for low beams and 9005 for high beams; fog lights commonly H11.
- HID-equipped models (if applicable): If your Equinox uses HID headlights, bulbs are typically paired with ballast systems (often D2S/D3S-type bulbs). Check your vehicle’s diagram to confirm the exact bulb and ballast configuration.
Note: Market and option packages can change headlight design, so always confirm with official documentation or a parts professional.
Summary
The Chevy Equinox does not have a universal headlight bulb. The right bulb depends on the exact year, trim, and headlight type (halogen, HID, or LED). To get the precise bulb number, identify your year/trim, consult the owner’s manual or GM parts diagrams, and verify by reading the bulb or using a parts finder. If you share your year and trim, I can provide the exact bulb size and cross-reference.
