Hello Martin,
I have to broadly agree with the other respondents, that it seems rather unnecessary to wish to have all your road lights on whilst parked up on site, but each to their own!
From a practical point of view, it is not to difficult to devise a scheme, and it would be similar to a job that a friend of mine needed when he had to park his trailer on the road outside clients houses. The road traffic act required that the side lights were on during the hours of darkness.
In his case we fitted a 12S socket to the front of trailer body, which was wired to an internal battery. The side light circuits were connected, so that when he parked up, he disconnected the trailers 12S plug form the truck, and plugged into the trailers 12S socket.
This was handy as it provided a proper stowage point for the plug, and it was easily disconnected during daylight or for towing.
The socket was also a handy 12V source for external equipment, like a work light, power tools etc.
If you are after making a light show, then with some electronics, you could create a running light effect by connecting each light circuit to a sequencer
