It depends on trim. Halogen low beams typically use H11, with high beams using 9005 and fog lights usually H11. If your Enclave is equipped with HID headlights, the low-beam bulb is a D1S or D2S-type bulb, while high beams remain 9005.
In this article, we explain the possible bulb types, how to verify your exact configuration, and where to find the correct information for your specific vehicle.
Possible bulb configurations
Below are the typical bulb types you might encounter on a 2014 Buick Enclave, depending on whether the headlights are halogen or HID.
Halogen headlights (common on base trims)
For halogen headlights, the low-beam bulb is typically H11, the high-beam bulb is 9005, and the fog lights (if equipped) are usually H11.
- Low-beam: H11
- High-beam: 9005
- Fog lights: H11
These sizes match many GM installations of that era and are the most common configuration for base Enclave trims.
HID headlights (optional on higher trims)
For HID-equipped Enclaves, the low-beam bulb is typically a D1S or D2S-type bulb, while the high beams use 9005. Fog light bulbs, if present as HID, may be HID or halogen depending on the exact packaging.
- Low-beam: D1S or D2S
- High-beam: 9005
- Fog lights: HID or H11 depending on option
Because HID systems can vary by production run and regional market, it’s best to verify with the vehicle’s manual or dealer resources for your exact car.
How to verify the exact bulb for your car
To ensure you buy the correct bulb, use these verification steps:
- Check the Owner’s Manual: The bulb sizes are listed for each lighting option.
- Inspect the bulb label: Open the hood and look at the bulb or housing for the size stamped on it.
- VIN-based parts lookup: Use GM’s parts catalog or consult a Buick dealer with your VIN for the precise match.
- When replacing, align with OEM or high-quality equivalents to maintain lighting performance.
Accurate identification avoids damage and ensures proper beam pattern and warranty coverage.
Summary
The 2014 Buick Enclave may use H11 low-beam halogen bulbs (with 9005 high beams and H11 fogs) or HID bulbs (D1S or D2S low-beams, with 9005 high beams). Confirm your exact configuration with the owner's manual or dealer resources for your VIN.
