For the 2019 Chevrolet Silverado 1500, the supplied fitment lists D5S bulbs for both the low-beam and high-beam headlights. This application does not include a separate halogen low- or high-beam size in the provided data. Confirm the headlamp assembly and existing bulb before ordering, especially if the truck has equipment that differs from the listed configuration.
Other notable exterior lighting sizes include 7443A for the front turn signals and front side markers, while the parking lights use 7443. At the rear, the tail and brake lights use 7444, and the rear turn signals and rear side markers use 7444NA. The reverse lights and center stop light use 921. The license plate lights take 2825, and the vanity lights use 6612F. No fog-light bulb is listed in the supplied fitment data, so fog-lamp compatibility should be checked separately if equipped.
