The indicator light is just to show that power has been enabled to the heating pads. It doesn't show when they are working and when they aren't. Most likely the bulb burned out but the circuit is still live. The heating pads will turn on and off from the enbedded t-stats to each heating pad. Mine burned out and I just replaced the switch so the light shows the circuit is turned on.

I found a replacement on ebay. I used the amber color so I could tell the difference at night whether I had the water pump on (red) or the heating pads on (amber). I used the A1-37 Switch.
Most RV Dealers will have this switch. Just be sure not to get a 120 Volt switch. They all look the same but on the side the voltage should read 12 volts.
