I want to get some kc daylighters for my truck (1993 f150). Will I be able to mount them directly to the front bumper?

 

I don't see why not. Most of the KC and other lamps have a single ~7/16" bolt to mount the lamp. Drill a hole where ever you like and mount them up. Then run the wiring harness. Putting them inside the bumper will require you to make a bracket, which isn't all that hard.

 

Ok thanks.
Now how should I wire the lights? Where should I run the power wire to? And should I run the cable into the cab and mount the switch?

 

KC should ship their lights with a relay kit. There will be a relay and switch, mount the relay in a dry spot under the hood, run the switches wires from the dash to the relay. Two wires to the battery and then hook up the lights to the relay.
