| They should be wired in parallel, not series.
But, 'twere it me, I'd probably do something like wire the outside 2 lights together, and then the inside 3 as a separate circuit. You could use a SPDT switch so that you could have either all 5 on, or just the outer 2 (or alternately, the inner 3).
Are there are wattage or amperage ratings on them? With that I could tell you what gauge wire to use to hook them up properly. You'll also definately be needing relays, don't try to do that setup directly from a switch. | |

| No markings or info on the lights. And when I said series, as in all hots together and all negative together.
I didn't get any relays or switches or wiring with it, just the bar and the lights(it was a good deal) So I'll need to pick up everything.
I do want to wire the outer two separate from the other three.

| Ahh, that's parallel wiring. Series is where the positive of one is wired to the negative of the next, and so on. Not very common in automotive applications.
I'll make a wild-ass guess that each light is 150W, max. Watts is Volts X Amps. So, with a 14volt system, thats a little less than 11 amps per light, or about 54 amps total draw. Because of the inrush current when you first turn them on, you'll probably want a 60 amp fuse.
This chart will help determine the proper wire size, looks like a 4 or 6 gauge wire is probably about right.
Length of run (in feet)
Current 0-4...4-7...7-10...10-13...13-16...16-19...19-22...22-28
0-20A.....14....12....12.....10......10.......8........8.....8
20-35A.....12....10.....8.....8.......6........6........6.....4
35-50A.....10....8......8.....6.......6........4........4.....4
50-65A.....8.....8......6.....4.......4........4........4.....2
65-85A.....6.....6......4.....4.......2........2........2.....0
85-105A....6.....6......4.....2.......2........2........2.....0
105-125A...4.....4......4.....2.......2........0........0.....0
