Chevrolet Silverado 3500HD 2017 Bulb Size
Bulb size chart
This page for the 2017 Chevrolet Silverado 3500HD helps you verify bulb sizes by lighting position, so you can match the correct replacement to the exact lamp on the truck. Because trim level, body style, and lighting package can change the fitment, it is best to use the bulb chart by location rather than assuming every Silverado 3500HD uses the same bulb.
For this model year, the listed bulb sizes cover common exterior and interior positions such as the low beam, high beam, fog lights, turn signals, side markers, brake lights, tail lights, reverse lights, license plate lights, and vanity mirror lights. Use the chart to narrow down the correct bulb before ordering, especially if you are replacing only one lamp or comparing multiple trim configurations.
Fitment can vary by market and equipment package, so always confirm the bulb in the vehicle before buying, especially on trucks with prior repairs or lighting upgrades. Some positions may use halogen bulbs from the factory, while others may have been converted to LED with aftermarket parts, which can affect compatibility, beam pattern, and warning messages. If your Silverado 3500HD has been modified, check the installed bulb type, connector style, and housing depth before purchase to avoid surprises during installation.
