Can you splice several lights onto one switch and/or splice them together so only one line goes to the battery?

 

Yes, you would have to figure out the draw of all the lights combined, find a relay rated for that amperage, and then buy wiring rated for that amount of draw as well.... it can be done. You can also have multiple relays triggered by one switch. How many lights were you thinking?

 

Well I will be running 4 up front and 2 rear but I think I would want the rear ones on a separate switch

 

I take it you are looking to mount 2 rigid duallys in the rear for backup and 4 duallys up front on windshield mounts?

Sounds great!

I have one d2 pointed out back and two d1's in the factory fogs, my next step will be two d2's on the windshield pillars
