If my math serves me corectly thats about $150.00 a tank? 4 sensors per tank I.E. Empty - 1/3 - 2/3- Full? I'm thinking no..... Have you ever thought about using a sensor cleaner a couple times a season, or don't throw TP in the tank, rather take out the trash every day? Personally I have a galley, a grey, and two black tanks. Oh yea I'm a full timer and I know how long it takes to fill each tank. A mod shouldn't cost $600 for led lights.. This is a no brainer... And, I rate this at one star....
