Switches?

[Fall]

Have 2 switches I cannot figure out. Both are 120 volt switches with a red indicator light on them. One is located on the side of the bath sink cabinet ( I think it may be the electric water heater switch ) and the other is in the bedroom on the end of the cabinet. ( is this a sump heater for the diesel engine) By the way the RV is a 2002 DAmon Escaper with a diesel. Thxs in advance

I have a 2004 Damon Escaper 4076. The one in the bedroom is probably the engine block heater. I have a 120 V switch with an indicator in the bedroom of our coach.

My guess is that the switch in the bath is the water heater but I am not sure. My switches for the hot water are located on a panel in the hallway of our coach.
