Most 2015 Chevrolet Silverado models with halogen headlights use H11 for low beams and 9005 for high beams. If your Silverado is equipped with factory HID headlights, the bulbs are typically D1S or D3S, depending on the production date and trim. Always verify with the owner's manual or the headlight housing label.
Headlight configurations can vary by trim level and options, so the exact bulb type may differ from one truck to another even within the same model year. Halogen setups are the most common, but some trims or packages include HID projectors that require different bulbs and ballast components. The best way to be certain is to check your manual or inspect the headlight assembly for bulb markings or the presence of a ballast.
Halogen headlights (most common)
Typical bulb codes
Below are the bulb types you’re most likely to encounter with halogen headlamps on a 2015 Silverado.
- H11 — low beam
- 9005 (HB5) — high beam
When replacing halogen bulbs, consider replacing both sides at the same time to maintain consistent brightness and color. After installation, verify proper alignment and aim of the headlights.
HID headlights option
Bulb varieties used in HID setups
For 2015 Silverados equipped with factory HID headlights, the bulbs are typically one of these, depending on the specific production date and package.
- D1S
- D3S
If you’re dealing with HID bulbs, it’s often wise to service the ballast and related ignition components along with the bulbs, and have a professional handle replacements to ensure proper wiring, ballast function, and beam alignment.
How to confirm your bulb type
To avoid guessing, use these steps to confirm the exact bulb type on your truck.
- Consult the owner's manual for the bulb specification and replacement procedure.
- Remove the headlight bulb access panel and inspect the bulb/socket; the label on the bulb or socket can reveal the type (H11, 9005, D1S, D3S, etc.).
- Look for a ballast if HID is installed; HID systems have a separate ballast module and wires, unlike plain halogen setups.
- Check your truck’s trim or build sheet (or VIN) to determine whether HID or halogen headlights were factory-installed.
If you still aren’t sure, contact a Chevrolet dealer or a reputable automotive parts retailer with your vehicle’s VIN for a precise match.
Summary
For the 2015 Silverado, halogen headlights use H11 (low beam) and 9005 (high beam). If your truck has HID headlights, the bulbs are typically D1S or D3S, depending on the specific build. Always verify with the manual or by inspecting the headlight housing and ballast to ensure you’re purchasing the correct bulbs.
