Hi Aposhark.
It was some time ago now that I bought the panels and lights but I remember just surfing caravan and boating websites to source the parts, looking for 12 volt lighting. The flourescent lights each had two tubes and they came with a switch built in. The leds were ok but to be honest they were expensive and nowhere near as bright as the flourescents. I would recommend you take a couple of 12 volt flourescents with you and spare tubes. But remember if you leave them turned on for to long and flatten the car battery it will kill the car battery, it will never recharge.
