The quick answer: most 2015 Chevrolet Silverados with standard halogen headlights use H11 bulbs for the low beams and 9005 bulbs for the high beams. If your truck has factory HID or LED headlights, the bulb types are different and not interchangeable with halogen bulbs.
Halogen headlight configuration (typical)
The vast majority of 2015 Silverados with halogen headlights use a two-bulb setup per side: one low-beam bulb and one high-beam bulb. The following designations appear on the bulbs and in service guides for the common trim configurations.
- Low-beam headlight: H11
- High-beam headlight: 9005 (also called HB3)
- Fog lights (if equipped): often H11 or 9006, depending on trim
Note: If your Silverado uses HID or LED headlights, the bulbs and replacement approach differ. Check the vehicle's owner manual or the label on the headlight assembly for the exact specification.
HID and LED headlight options
Some 2015 Silverados came with factory HID headlights or LED headlights. In those cases, you won't replace a simple halogen bulb—you'll have HID bulbs such as D3S or D2S along with a ballast, or an LED module. Availability of genuine replacement bulbs depends on the exact configuration and trim level.
To verify whether your vehicle uses halogen, HID, or LED headlights, consult the owner's manual or inspect the headlight system label found on or near the headlamp assembly.
How to identify and replace the right bulb
Use these steps to confirm the correct bulb type and perform a replacement correctly.
- Turn off the vehicle and open the hood to access the headlight housing.
- On the rear or side of the headlight, locate the bulb socket or label on the bulb base to read the bulb type (e.g., H11, 9005, D3S).
- If you’re unsure, remove the existing bulb carefully and read any markings; compare with the vehicle manual or an online parts catalog for your VIN.
- Purchase the correct bulb type from a reputable retailer, and consider replacing both bulbs on the same side or both sides to maintain consistent brightness and color temperature.
- Follow the specific replacement procedure for your headlight assembly to avoid damaging clips or wiring.
Replacing bulbs in pairs helps maintain even lighting and color; always handle bulbs with clean gloves to avoid oils from your skin affecting bulb life.
Summary
In short, a 2015 Chevy Silverado with standard halogen headlights typically uses H11 for the low beams and 9005 for the high beams. If your Silverado has HID or LED headlights, the bulb types are different, often requiring D3S/D2S HID bulbs or a whole LED module. Always verify with the owner's manual or the headlight label for your exact trim and options before purchasing replacement bulbs.
