What you can't see can hurt you and this is an extra truth for diesel trucks. Whether you need some extra lumens from your factory lights or you just need replacements, Oracle Lighting's High Powered Fog lights are a fantastic upgrade that can operate under any conditions. Using the same factory mounts these fog lights are a snap to install with plug-and-play wiring connections. Oracle Lighting's LEDs push out approximately 1500 lumens while only drawing 15W of power so you can light up your campsite without draining your battery fast. Each light uses a PMMA lens, a Polycarbonate lamp, and epoxy-sealed electronics so these lights will last way past the time your factory installs would have fizzled out. Plus, the aggressive blacked-out look gives your Sierra a sharp look on top of the increased visibility.
