Find LED headlight bulbs for GMC Sierra, Canyon, and Terrain vehicles. This collection includes single-pair replacement bulbs, two-pair high/low-beam combinations, select fog-light bulbs, and CANbus decoder accessories.
Start with the vehicle selector. Enter your year, model, and light position, then confirm the number printed on your original halogen bulb before ordering. A matching socket alone does not guarantee the correct beam position, housing fit, or electrical compatibility.

| What you need | Options found in this collection | Confirm before ordering |
|---|---|---|
| One headlight position | H11/H8/H9, 9005/HB3, 9006/HB4 and other single-pair bulbs | Exact year, model, trim, and high- or low-beam position |
| Separate high- and low-beam replacements | 9005/H11 and 9005/9006 two-pair combinations | Both factory bulb numbers and the package contents |
| Other supported socket choices | 9012, H4, H7 and additional sizes shown in the filters | The number on the original bulb and product-page compatibility |
| Fog-light replacement | H10, H11, 5202, 880, and 9006 options | Verify the fog-light position separately |
| Electrical correction | C20 CANbus decoder options | Only add a decoder when the vehicle or product instructions indicate one is needed |

Fitment still varies by year, trim, housing, and beam position, so verify the original bulb before choosing a replacement.
Choose a single pair when you are replacing one confirmed light position. Choose a two-pair headlight bulbs bundle only when your GMC uses separate high- and low-beam bulbs and both listed sizes match the vehicle.

If an LED bulb flickers or produces a dashboard warning after installation, verify the connection and vehicle compatibility before adding a CANbus decoder.
Confirm the year, model, trim, and light position.
Read the bulb number on the original halogen light.
Check rear housing clearance and dust-cap space.
Verify whether the bulb uses a direct plug or external wiring.
Confirm whether the package contains one pair or two pairs.
Check beam alignment after installation to avoid unwanted glare.
No. Bulb size and light position can vary by model year, trim, and headlight housing. Use the vehicle selector and verify the original bulb number.
Select the vehicle year and model, choose the high-, low-, or fog-light position, and compare the result with the number printed on the factory bulb.
Do not assume they are. They have different applications, and your GMC may use one size, both sizes, or another configuration.
