Bulb size chart
This page helps you verify the bulb sizes for the 2019 Chevrolet Silverado 1500 by lighting position, so you can match the correct bulb to the exact lamp on the truck. Because Silverado trims and lighting packages can vary, it is best to confirm the bulb type for each location before ordering replacements.
For the 2019 Chevrolet Silverado 1500, the chart covers common exterior and interior positions such as headlights, brake lights, tail lights, turn signals, side markers, license plate lights, reverse lights, and vanity mirror lights. Using the correct bulb size for each position makes replacement faster and helps avoid fitment issues.
Fitment can differ by trim, cab style, bed length, market, and factory lighting package, especially when comparing halogen and LED-equipped trucks. Some Silverado 1500 models may also have aftermarket conversions or replacement housings that change the bulb requirement, so it is smart to check the installed bulb before buying. If your truck has been modified, a bulb listed for the original factory setup may not match the current lamp assembly.

What is the brake light bulb size on a 2019 Silverado 1500?
