hope this is in the right place, im after a wiring diagram of how to wire in my light bar. it has 4x 100w bulbs, now i no these are illegal to use on the road. ideally what i would like to do is wire them into my main beem but with a switch, so i can still use main beem on the road but when im off road can flick the main beem on and then switch the for the light bar. i thought this would be quiet easy and just splice into the wires by the head light, but from research on the net it seems i need relays 1 to each pair of lights. if someone could draw me a basic drawing that would be fantastic. thanks in advance
