Chevrolet Silverado 3500HD 2014 Bulb Size
Bulb size chart
This page covers the bulb sizes for the 2014 Chevrolet Silverado 3500HD and organizes them by lighting position so you can quickly confirm the correct replacement before you buy. Whether you are changing a headlight, a marker lamp, or a cabin bulb, using the right socket and bulb type helps keep the truck’s lighting working as intended.
The 2014 Chevrolet Silverado 3500HD uses different bulb sizes depending on where the light is located, and some trims or lighting packages may change the setup. That is why it is important to match the bulb to the exact position on the truck instead of assuming one size fits every lamp on the vehicle.
For best fitment, compare the bulb chart with your truck’s trim, body style, and lighting package, since equipment can vary by market and configuration. Some positions may use halogen bulbs, while others may be listed as LED or may have been converted with aftermarket parts. If your Silverado has been modified, especially in the headlight or fog light area, verify the installed bulb before ordering so you do not end up with the wrong base, size, or connector. Checking the old bulb number and the socket style is the safest way to avoid returns and ensure a proper replacement.
