Which Chevrolet Silverado 1500 model years does this cover?

These headlight bulbs specifications apply to every Chevrolet Silverado 1500 built from 2014 through 2018 — the K2XX (3rd generation), full-size half-ton pickup (regular, double, crew cab).

What headlight bulb does a 2014–2018 Chevrolet Silverado 1500 use?

H11 (halogen, 2014–2015 and lower trims 2016–2018) for the low beam and 9005 (HB3) for the high beam. Trims with factory LED or HID projectors use a sealed assembly instead and are not bulb-serviceable.

What fog light bulb does a 2014–2018 Chevrolet Silverado 1500 take?

5202 (where equipped).

Can you put LED bulbs in a 2014–2018 Chevrolet Silverado 1500?

Physically, yes, LED replacements exist in every common base. Whether they work well depends on the housing: a reflector housing designed around a halogen filament scatters LED output into oncoming traffic instead of down the road. Projector housings tolerate the swap far better. Some vehicles also flag the lower current draw as a bulb-out fault.
