Nice one 👍 I've used diodes on my int lights so I can power them from Phoenix or leasure system with no back feed issues if I have both switched on for some weird reason 🤔

[@CriftinsCampers]

I suspect the supply at the highest voltage wins if both feeds are powered up together. I have kept the scene lights wired up to Genisys in the iveco but will probably be using diodes rather than relays this time to have them come on when in Reverse.

@CriftinsCampers I kept my scene lights on Phnx as well but I put LED strips in there as well powerd from the leasure system, simply to save power, the bulbs they use are a bit power heavy and bright for camp illumination 🤔
