When you turn on your clearance lights the backlighting in all your gauges and switches should light up. It's not that this circuit has anything to do with the clearance lights themselves. If the clearance lights are not on then you shouldn't have any backlighting in ANY of your switches or panel gauges. You certainly shouldn't have anything lit up when nothing it turned on, this would just be a load on the battery when in storage that is not right. This was my point.
That said it is not uncommon to have a bad battery with a bad cell in it that can cause all kinds of screwy things to happen. For instance our starting battery went bad on our rig and I found out because the LED turn signal lights that ring our side view cameras were on for no reason. They should only be on if a turn signal is on. The rig was in storage and nothing turned on. Wierd! As soon as I replaced the battery everything was fine.
If the light is lit up in the switch when nothing is on, perhaps that is the way they intended it to be but from my point of view that is poor design. I don't want anything draining my battery when in storage even a little light in a switch...
