You should never wire directly to the battery as indicated. It should go through a relay and fuse and legally must be wired into the headlights high beam so the the driving lights go off when you dip your lights or switch them off. Like this:
But don't delete the bit inside the box.

or as I did just put "driving lights circuit" into a Google image seach.
It's a safety issue; driving lights draw a very high current and this should not be made to travel through long or thin wires into a switch in the cabin; using a relay sited close to the lights and battery and using short high ampage cable to connect the lights and battery to the relays means no overstresed wires and engine bay or cabin fires.
