I knew I wanted to throw out the factory fog lights and put the Light Canons in. I also knew I wanted to make the install as easy as I could. Since the Jeep already had factory-installed light stuff, I just wanted to reuse it. The first thing I needed to do was to make sure that the new lights don’t use more power than the factory circuit is set up for. In this case the factory fuse is a 20 amp fuse and the new lights are rated to use 4.16 amps. My rule of thumb is that as long as the new stuff uses half or less than the circuit is setup for, it is OK.
