Jackie helped me sort out the lights, since she's an electronics engineer by trade. We've mounted the strobes to a piece of board along with the power supply and a switch. At the moment, ironically enough, it is power from some 16V batteries from a defibrillator (Jackie works at a hospital as a biomed). Ironic, because batteries that once powered something to save you from a heart attack, now power something that could give you one!! I'd like to have got a photo of the strobes in action, but it would have buggered the camera; best I could do was one of the garage being lit up!!
