Hello! I was tiring to find out what causes the lights in my house to dim then go back to normal. This happens all day long.. I can't figure it out. Thanks! :p

There is a loose or corroded connection somewhere in your electrical system. It can be at the utility transformer, the connections where the utility lines connect to you home, the meter, the panel, the main breaker, or even just one bad breaker for one circuit.

This really requires a good service troubleshooting electrician to come out and check your entire system, he should also have the utility company there at the same time to check their connections and inside the meter.

This will not get better on it's own.
