O.k. my advice is to use an illuminated switch so you can tell they are on or off. How you power them is up to you. Ask yourself how you're going to use them - driving only, use them if you're stationary with the engine off, as extra forward lighting with your headlights etc. I would not run them straight off the battery with a switch as you can easily forget to turn them off and leave the truck. Hook up the lights using a relay from the battery and then use power from whatever powered circuit works best for you. On accessory power so if you forget to turn them off and pull the keys out, they die - from the main ignition circuit so they only work when the engine is running - from the headlight circuit so they only work with the headlights etc.

I found a circuit diagram that best explains how to use a relay in auxiliary driving lights -

it looks a little tricky with the relay in the circuit but once you take a look at a relay and see the numbers underneath it next to the terminals it's a cake walk. Power off the battery with a 25A fuse, power from another circuit to act as a 'trigger' which will pull minimal current from that circuit with a low amp fuse just in case. Hope this makes sense to you.
