Which Chevrolet Silverado 1500 model years does this cover?

These headlight bulbs specifications apply to every Chevrolet Silverado 1500 built from 2012 through 2013 — the GMT900 (2nd generation), full-size half-ton pickup (regular, extended, crew cab).

What headlight bulb does a 2012–2013 Chevrolet Silverado 1500 use?

H11 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.

5202 (where equipped).

Can you put LED bulbs in a 2012–2013 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.
