S1 Dual Fog Pocket Kit for GMC Sierra HD

S1 Dual Fog Pocket Kit, fitment-checked

Dual means two S1 units per side rather than one. The small light doubled up to fill a pocket a single larger one would not suit.

The S1 is the smallest light in this range, and a dual kit puts two of them where another kit would put one bigger unit. That suits a pocket whose shape favours width over height, and it lets the pair carry a multi-pattern output between them. Coverage is the GMC Sierra 2500 HD and 3500 HD from 2020 to 2023, both on the same span with no trim condition. Lenses are amber. An install guide is available, which is worth having with twice the number of lights to place.
