Default Wiring up multiple sets of Rigid Duallys?

I have a second set of Duallys arriving in the mail soon. I was just curious how others wired up multiple sets of Duallys. Can you hook both sets up to the same battery terminals? Will they work off of the same switch even though only one set of wires are hooked to it?

Thanks!

The Rigid website lists the current draw to be 1.45 amps per light. 1.45 x 4 is 5.8 amps, which is a little above the current rating of the 16 gauge wire they provide. A single switch could handle the current.

I ran mine with some 14 gauge wire I had from the point that I spliced the four lights together to the switch, battery and ground.

The D2s draw 2.5 amps per light and should use 12 gauge wire.

Thanks for the rundown. I'd like to avoid wiring the two sets together if possible. Can I just connect the two sets to the battery and still have them operate off of the same switch?

The power for the lights go through the switch before it hits the battery. So the current for all for lights would go through the switch.

Below is what I did.

Battery----Switch----splice to 4 lights----splice to ground----Ground

From the battery to the "splice" is a single wire that I ran from fuse box under the hood into cab to the switch and back under the hood. This wire was 14 gauge as it handles the current of all 4 lights.

From the splice to the lights, I used the wire supplied by Rigid.

After the lights I spliced all the wires back to one 14 gauge wire and then to ground. All the splices were under the hood.

s.whiplash thanks for all of the information. It looks like my lights are waiting for me at the post office so I'll pick up some 14 gauge wire tomorrow and wire them up.

Be sure to put a fuse coming right off the positive terminal off the battery if you don't have one and be sure to size it just larger than your current load.

The Dually wiring harness comes with a fuse. And I have no idea what's going on in the diagram above, LOL. I have NO CLUE about wiring.

I installed the lights this evening and just ran another set of wires into the cab to a second switch. Everything works great.
