On a 2020 Silverado, headlight bulb configurations vary by trim and option package. The most common setups are halogen headlights on base models and LED headlights on higher trims; some packages may also include HID headlights. This article explains the typical bulb types and how to identify them in your vehicle.
Halogen headlights: common on base trims
If your Silverado uses halogen headlights, you replace individual bulbs rather than the entire headlight unit. The typical bulb types used in this setup are:
Common halogen bulbs for the 2020 Silverado include:
- Low beam: H11
- High beam: 9005 (HB3)
- Fog lights: H11 (where equipped)
Note: Actual bulb part numbers can vary by production date and region. Always verify with the owner's manual or GM parts catalog for your exact VIN.
LED headlights: higher trims and options
Some 2020 Silverado trims upgrade to LED headlights, which use integrated LED modules rather than standard replaceable bulbs. In these systems, there are typically no separate bulbs to swap out; if an LED module fails, you may need to replace the entire headlight assembly or the module itself, depending on design and warranty terms.
Key points for LED headlights:
- No user-replaceable bulbs in most designs
- Headlight assemblies or modules may be serviced/replaced rather than individual bulbs
- LED trims are common on LTZ, Trail Boss, and higher-end configurations
Always confirm with the dealer or owner's manual which headlight type your truck uses, as trim and options change across production years.
How to identify your exact bulb type for your Silverado
To know your exact bulb configuration, use these checks:
- Inspect the headlight housing: a clearly labeled LED assembly usually has a distinctive look and may bear an "LED" badge; halogen housings use a traditional bulb with a visible filament inside.
- Check the door jamb sticker or owner's manual for the recommended bulb types for your trim and VIN.
- Refer to the GM parts catalog or contact a Chevrolet dealership with your VIN for the precise bulb numbers.
Conclusion: Understanding your headlight type helps you buy the right bulbs or plan if you need to replace an entire headlight assembly. Always cross-check with official sources for your exact vehicle configuration.
Summary: The 2020 Chevy Silverado’s headlight bulb setup varies by trim—halogen bulbs (low beam H11, high beam 9005, fogs H11 where equipped) are common on base models, while higher-trim versions may use LED headlights with no replaceable bulbs. For exact part numbers, consult the owner's manual or dealership with your VIN.

What's the worst year for Chevy Silverado 1500?
Worst Years for the Chevy Silverado 1500
- 2007–2011 (early GMT900) – Known for AFM oil use, lifter noise, and costly engine repairs.

- 2019–2021 (early T1XX) – DFM lifter failures and engine bearing issues that led to recalls.
Do I need H11 or 9005?
H11 bulbs are designed for use as low beam headlights, while 9005 bulbs are typically used for high beams. This results in a higher brightness level for the 9005 bulbs compared to the H11 bulbs.
Are 9005 and H11 the same?
Difference between these bulbs will be the O-ring on the base. H11 on the left side will have a big pronounced O-ring on the base of the bulb versus the 9005.
