1999–2021 Chevrolet Silverado 1500: the practical LED headlight and fog-light reference

The Silverado 1500 changed lighting layouts more than once across these model years. Instead of presenting a full vehicle bulb chart, this guide stays focused on the positions Luxster owners care about most: low-beam headlights, high-beam headlights, and factory fog lights. It is designed to help you identify the right starting point before selecting an LED replacement.

Check before you buy: The same Silverado year can have different trims, headlamp assemblies, and factory lighting packages. Confirm the marking on the original bulb and your owner’s manual. A factory HID D5S system is not a direct plug-in LED-bulb application.

Silverado 1500 headlight and fog-light size roadmap

Model years Low beam High beam Applicable series
1999–2006 9006 / HB4 9005 / HB3 Applicable to all series
2007–2021 H11 9005 / HB3 Applicable to all series

What changed across the Silverado generations?

For the earlier trucks in this guide, 9006 low beam and 9005 high beam are the key headlight references. From 2007 onward, H11 becomes the common halogen low-beam reference while 9005/HB3 remains common for the high beam. Later trucks need a closer look because some trims use D5S HID assemblies instead of halogen bulb positions. In those years, checking the actual headlamp assembly is more reliable than buying by model year alone.

Choose a Luxster LED headlight route after confirmation

Headlights and fog lights do different jobs

Low and high beams are aimed to carry useful light farther down the road. Factory fog lights sit lower and are intended to support near-field visibility in poor weather. Treat them as separate lighting positions: verify the correct base and connector for each one, and recheck headlight aim after any headlight-bulb installation.

Four checks before installation

  1. Confirm the exact model year, trim, and headlamp technology—not just “Silverado 1500.”
  2. Read the bulb number printed on the factory bulb you remove.
  3. Verify that the truck has factory fog lamps before choosing a fog-light size.
  4. After installation, test both beam functions and check headlight aim before driving at night.

The Luxster takeaway

For the 1999–2021 Silverado 1500 configurations covered here, the common halogen headlight path is usually either 9006 + 9005 or H11 + 9005, depending on generation. Confirm the original bulb and headlamp technology first, then select the matching LUXSTER option.
