If your DH is handy, like mine is, he can put a lighted switch inside. He located ours on the front of our sink which also contained an outlet. He got a new 4-gang electrical box, ran the wires under the sink and put the outlet in one side and the lighted switch in the other. Now we can see at a glance if the water heater is on! Since we don't drain the water heater after every trip (we're using the TT almost every weekend) there is no chance we'll turn it on with no water in it. I love it!! I dont' have to ask him to turn the water heater on, and it is one of the things on my checklist to take care of so we'll have hot water just a short time after arrival.
