I need some help from all the electrical experts. I purchased replacement headlights with LED Halo lights. The headlights are plug and play. There are 2 integral Halo light strips with 4 wires (2 red & 2 black). The maker is United Pacific. I plan on running the Halo lights on a separate circuit with a switch so I could turn them on & off separately from the headlights. My question is what is the best way to wire up the Halo lights. I know that I can run a wire from the battery with fuse to the switch on the dash and then wire to each set of Halo lights with ground. Is that the best way or is a relay needed. That's where it gets dicey for me. I don't exactly understand the need and workings of a relay. If I need a relay, a wiring diagram would be useful. See pics below of the front and back of the headlight.IMG_2900 (1).JPGIMG_2901 (1).JPG
