The 2015 Chevrolet Silverado 1500 offers a variety of lighting configurations depending on the trim level, package, and whether the truck came with halogen or projector-style headlights. This guide will help you navigate the different bulb sizes for your specific Silverado.
OEM Differences: Halogen, Projector, and LED
Most 2015 Silverado 1500 models came equipped with traditional halogen headlights. However, certain trim levels (such as the LTZ and High Country) might have featured projector-style headlights for the low beams, utilizing an H9 bulb, or even High-Intensity Discharge (HID) lighting with a D5S bulb for an enhanced lighting experience.

All other exterior lighting, including high beams, fog lights, turn signals, brake lights, tail lights, reverse lights, and license plate lights, were predominantly halogen across all trim levels.
