My first impression was: I am missing a separate ground for the relay control and for the arduino! However, after some study I discovered that you CAN operate the board with galvanic isolated 12 V and the arduino's 5 V. How? Don't use the straps!! So don't connect the 4 middle pins with straps to Ground or to VCC of the relay module, but connect these

Fitting a commercially available "lights" module into the car may have fixed this but the power to supply it is fed from the car battery and I wanted to isolate the caravan lights from the car lights. I could have bought and fitted the commercial "lights" module into the caravan but they are
