The after market fog lights are fully enclosed. Just need a good 12V source not to mention a switch location. These should come with a relays

Driving lights work kind of in conjunction with the brights, for just more light. Mount two street legal 55 watt lights on your bully bar, or at least on top of the bumper. Turn off with oncoming traffic.

True fog lights are a pair of 55 watt white lights that casts a flat beam, must shine low under the fog and close to the road with some light shining on the road to see the lines but not cause a reflection back up to the fog. The perfect place would be in front of the bumper (bad idea) or below the bumper. When aimed correctly fogs can stay on with oncoming traffic. The key is a proper beam spread.

Edit add: I think most of aftermarket fogs are meant to be mounted upright, on top of, but check.
