Most 2006 Chevrolet Silverado headlight assemblies use a separate H11 low-beam bulb and a 9005 high-beam bulb; fog lights—if equipped—use H3. Some trucks or aftermarket upgrades may differ, so check your owner’s manual or the label on the headlight housing for your exact fit.
Overview of standard bulbs
This section lists the bulbs commonly found in the factory headlight assemblies for the 2006 Silverado.
- Low beam: H11
- High beam: 9005 (HB3)
- Fog lights (if your truck is equipped with them): H3
Note: Some special editions or regional variants may have different configurations, and aftermarket replacements may substitute LED or HID versions. Always verify with the exact VIN or owner's manual.
Alternative options and aftermarket considerations
Owners often upgrade to brighter lighting via HID or LED replacements, but there are important compatibility considerations.
- HID kits: Not all factory headlight housings support HID; improper installation can cause glare and moisture issues.
- LED bulbs: Many LED replacements exist for H11, 9005, and H3; ensure proper heat sinking and beam pattern to avoid misalignment.
- Fog light variants: Some drivers replace H3 fog bulbs with LEDs or incandescent upgrades; check the fixture size and wiring.
Before attempting any aftermarket upgrade, check local laws and ensure the kit is road-legal in your area and that your headlights will properly align.
How to verify the exact bulb type for your Silverado
To confirm the precise bulb types in your specific vehicle, use these steps:
- Consult the owner's manual or the GM parts diagram for your exact model and trim.
- Inspect the back of the headlight housing for bulb type stickers or markings.
- If replacing with stock bulbs, purchase by the bulb base size (H11 for low beams, 9005 for high beams, H3 for fog lights if present).
- When in doubt, remove a bulb and compare the base shape with the replacement bulb or bring the old bulb to a parts store for matching.
Following these steps helps ensure you get the correct bulbs and avoid fitment issues.
Summary
The 2006 Chevy Silverado’s standard headlight setup uses H11 low-beam bulbs and 9005 high-beam bulbs, with H3 fog lights if your trim includes them.

Always check the owner's manual or the headlight housing labels to confirm the exact bulb type for your particular vehicle.
