Abi lights

Hi. I have an Abi Herald Jubilee which is 1993 and even with a new battery the lights only work when the van is plugged in.

I know there 12 volt but im thinking its been wired to work through the zig as it was used to live in for a while and i was wondering how easy it would be to make them run from the battery as they should?

Many thanks Conrad
