Chevrolet Silverado 1500 2011 Bulb Size
Bulb size chart
This 2011 Chevrolet Silverado 1500 bulb size guide is organized by lighting position so you can quickly verify the correct replacement bulb for each exterior and interior lamp. Whether you are replacing a headlight, tail light, license plate lamp, or cabin light, this page helps you match the bulb size to the exact location on the truck.
The Silverado 1500 was offered with different trim levels, body styles, and lighting packages, so bulb fitment can vary by configuration. Use the chart on this page to compare the bulb type for each position before you buy, especially if you are replacing a single bulb or updating more than one light at the same time.
For the best fitment results, always confirm whether your truck uses halogen or LED lighting in a given position, since some locations may have been changed with aftermarket parts or factory package differences. This is especially important for daytime running lights and fog lights, where LED conversions are common but may require different hardware or compatibility checks. If you are unsure, remove the installed bulb and compare the base and markings before ordering, because the same 2011 Chevrolet Silverado 1500 can have different bulbs depending on trim, market, and body style.
