gday all, question for the day, can i run a set of 35w hid lights and a 24 " lightbar off the one battery...? too much draw or should i set up dual batt. cheers. Also, ive wired the hid and bar together through the one relay/switch.... bad idea?

Assuming the lightbar is 120W or thereabouts that will take 10A, the two HID spotlights will pull 6A or so. Total demand of approximately 200W. As long as the wiring and relay is up to the task there are no problems, same as running two 100W halogen spotlights.

As mjrandom said, no issues and no need for a 2nd battery unless you're going to be using the lights for an extended period of time with the engine off.
