Typically, the 2014 Chevy Silverado uses H11 for low-beam headlights and 9005 for high-beam headlights; fog lights, when present, commonly use H11 as well. If your truck has factory HID headlights, the bulbs are HID types such as D1S or D2S rather than halogen. Always verify with the owner's manual or the labeling on the headlight housing for the exact bulb type.
Halogen headlight setup (most common)
The following list covers the standard halogen system you’re most likely to encounter on a 2014 Silverado.
- Low beam: H11 (55W)
- High beam: 9005 (HB3, 65W)
- Front fog lights: commonly H11, though some trims may use 9006 (HB4) or other bulbs; verify your specific vehicle
Note: The fog light bulb type can vary by trim and production date; verify the exact bulb type for your vehicle before purchasing replacements.
HID headlight option (less common)
If your Silverado is equipped with factory HID headlights, bulb types differ from halogen units and require the appropriate HID bulbs and ballast.
- Low beam HID: D1S or D2S (depending on the headlight assembly)
- High beam: may be integrated with the HID module or use a separate bulb depending on design
For HID-equipped vehicles, replacement bulbs are not interchangeable with halogen bulbs; consult the owner's manual or GM service information to confirm the exact bulb type and ballast compatibility.
Where to confirm the bulb type
Best practice is to check the inside of the driver’s door jamb for a specification sticker, the owner’s manual, or the headlight assembly labeling. When replacing bulbs, match the base, size, and wattage to the OEM specification noted on these sources.
Summary
Most 2014 Silverado models use H11 for low beams and 9005 for high beams in halogen setups, with fog lights typically using H11. If your truck has factory HID headlights, you’ll be dealing with D1S/D2S HID bulbs instead of H11 or 9005. Always verify with the manual or the vehicle’s labeling to ensure you buy the correct bulb type.
