The correct bulb depends on your headlight type. If your truck has halogen headlights, the low beam uses H11 and the high beam uses 9005. If your Silverado 2500HD uses LED headlights, there are typically no replaceable bulbs for the main beams; the headlight assembly or LED module is replaced instead. Always verify with your vehicle’s VIN or owner’s manual to confirm the exact part.

Before listing typical bulb sizes, note that your exact configuration may differ by trim or market. The following are common halogen setups seen in similar GM trucks of this era.
- Low beam bulb: H11

LED headlights on the 2024 Silverado 2500HD
Service and replacement considerations
Many 2024 Silverado 2500HD models with LED headlights use a module-based design. In these cases, there isn’t a simple bulb to replace for the main headlamp. Replacement typically involves the headlight assembly or a sanctioned LED module, obtained through GM parts or a dealer, and matched to your VIN.
- There is usually no separate replaceable “bulb” for the main LEDs
- If an LED component fails, you’ll likely replace the entire headlight assembly or the approved LED module
- Other lighting components (like daytime running lights or accent LEDs) may have separate replacement parts depending on design
Always verify part numbers with GM Parts or your dealer using your VIN to ensure compatibility and warranty considerations.
How to verify the exact bulb or replacement part for your vehicle
To ensure you purchase the correct part, follow these steps:
- Consult the owner’s manual for the correct bulb type and replacement procedure for your trim
- Inspect the headlight housing or existing bulb for any stamped part numbers or labels
- Use your VIN on the GM Parts catalog or with a Chevrolet dealer to pull the exact bulb or assembly part number
- Contact a GM-certified technician if you’re unsure about LED versus halogen vs. mixed configurations
These steps help ensure compatibility, prevent incorrect purchases, and maintain lighting performance and safety.
Summary
For the 2024 Chevy Silverado 2500HD, there isn’t a single universal bulb solution. Halogen-equipped trucks typically use H11 for low beams and 9005 for high beams, with potential variations for fog lights. LED-equipped models generally require replacing the headlight assembly or an approved LED module rather than a replaceable bulb. Always verify the exact part using your VIN and official documentation to ensure a correct and safe replacement.
