radio shack # 276-1661 50v 6a diode. $2.49. cheaper than a relay. if your gona add a relay make it water proof if your gona add one. if the relays not sealed and you go mudding or leave it sit outside the relay will fail from moisture. also if your worryied about it drawing to much power add another diode. 12amps is more than enough to run the low beams.

they need to make the headlight pods bigger. iv got 2 water proof relays, and a tone of wire in my headlight pod.
