QUESTION: yeah it's electrical have you ever heard of this  situation before  any ideas on what it would be a panel of some sort, circuit  loose wires etc

Answer
You might look for some visible wiring damage, if there are rodents around the area they like to chew on wiring insulation especially under the hood, take a look at the engine wire harnesses, open the fuse box and check the fit of all fuses in their sockets, move some wires and relays around to see if you can duplicate the condition or turn the lights off, check all ground connections, check electrical connectors,  good luck.
