Rear view cameras and L E D circuits

[DaveA1]

I take that it is not possible to wire a rear view camera to a LED lighting circuit (rear number plate light)as they run on a lower voltage?

Caravan LED lights run on 12v however they draw much less current and that might interfere/confuse the canbus and/or lamp failure system.
Best bet is to find where the permanent 12v from the car branches inside the caravan and take the feed from that.

On my Bailey there is a fuse block directly behind the A frame just behind the front wall. I took a two strand cable (feed and earth) from that and ran it down and under the floor to the back where I took it up inside a wardrobe, to feed my (wireless) rear view camera. It works a treat.

That means my camera is only live when the caravan is plugged into the car, so no fear of inadvertently flattening the leisure battery. I just have to remember to disconnect car and caravan when on a long ferry journey, like to Spain. It also disconnects the ATC which could also flatten the car battery over 2 days.

Mr. Plodd makes perfect sense.
