1. The reason for indicator light is to tell if any of the GFI's are tripped.
2. The reason for more then 1 heater is in case 1 goes bad I can hope fully catch it before my tank cooks or freezes. Another is that original the tank was a fish only and was covered. I had to buy another due to the increase load. Also I do not heat the room the Tank is and the temp can fall to low 60's So I had to add yet another.
