Reviving an old thread I know, but it's closest to what I'm attempting at the moment, so if there's anybody still around in here, I'd appreciate some help.
I have two 5w 12v lights, and two 6v batteries (the chunky spiral ring torch kind) which I plan to run in series to get the 12v. Somewhere in there I will want to include a switch. I like the one Andy linked to so may go for that.
My question is, how do I work out what wire cable I should use?
The lights each have a thin black and a red wire attached, ending in alligator clamps (which I'll probably have to remove to put those into a switch). The wire might be long enough to reach a switch, but I'll still need to get more wire to go between the switch and batteries, and that's where I'm getting muddled.
They lights are not exactly the same as this, but very similar.

Appreciate any help, thanks.
