Any suggestions on why the 12volts led lights in our van, when on keep dimming then turn brighter while on. I have racked my brain, but still Cann't work it out. What could be done to stop this from occurring? Thanks in advance.

Is it from when your fridge cycles on / off?

Ditto, mine do it also, especially when the voltage gets down a bit.

Some of my LEDs flicker a lot, is that the same thing?

Probably the voltage. Put a multi meter on it and watch when the lights dim and when they are bright. It's probably your charger cycling on or off if it's when you are plugged in to 240 volt power.

Sounds like there is something cycling on the system. Keep an eye on the battery charger cycling on and off (you pick this by the system voltage rising above 13 V.) Apart from a compressor fridge do you have anything else like a DC water heater for the sink?
