Why do the lights in the house get brighter or dimmer?
The lights in the house get brighter or dimmer according to the balance of loads between the red and black legs. When the load on one leg, say the black one, is greater than that on the red leg, the voltage drop causes lights on the black leg to dim.
Why do the lights on the red leg get brighter?
At the same time, the lights on the red leg get brighter than they should because the effective voltage is greater than 120 volts. The load balance changes when you turn lights or appliances on or off.
Why do my lights dim when I turn them on/off?
When the load on one leg, say the black one, is greater than that on the red leg, the voltage drop causes lights on the black leg to dim.

Yes, flickering lights can be a warning sign that there is a fire hazard in your home. When lights flicker all over the house and are not associated with a large or major appliance, such as an air conditioner, turning on it could mean that there is an issue with the wiring, which could cause a fire.
Can a power surge damage house wiring?

Why do lights brighten when appliance turns on?
If both lights and refrig were drawing about the same current they would see the same voltage, and the neutral would see little current. When the compressor kicks on and draws more current, the voltage divider is changed, the refrig will see less voltage and the lights see more voltage.
Should my lights dim when I turn on appliances?
If your lights flicker or dim whenever you turn on an appliance (e.g. a washing machine, vacuum cleaner, or microwave) then you're beginning to overload your circuit. Each home electrical circuit has a limit on just how much power it can draw.
Why do my lights flicker every night at the same time?
There are any number of potential problem areas: a switch failure, loose fixture wiring, worn connectors in the breaker box, or loose service conductors in the main electrical panel. Contact an electrician ASAP if you suspect loose wiring or haven't found another cause for your flickering lights.

These power surges are far from harmless. They can damage your electrical outlets. They can fry your appliances and electronics. They can even start a fire.
Can sudden surge of electricity cause fire?
A strong surge can cause an appliance to overheat or even catch fire. The more severe the surge, the more likely it is to cause overheating and a fire. Switching appliances on and off doesn't cause as severe of a spike as, say, a lightning strike, but all surges carry a small risk of fire.
When a light bulb is cleaned, does it get brighter?
