Similarly one may ask, are dimming lights dangerous?
Old, damaged, or poorly installed wiring is a common cause of dimming house lights, and can be one of the more dangerous causes. Frayed or damaged wiring can sometimes lead to dimming and is extremely dangerous. If you suspect faulty wiring you should always contact a licensed electrician as soon as possible.
Additionally, why do my lights dim when I use my iron? A browning down (dimming) of lights is caused by a reduction in voltage, usually due to a large load being introduced into to the electrical system. Or when you plug in the iron in your bedroom (a resistant heat load) the bedroom lights dim or "brown down".
Consequently, will a bad ground cause lights to dim?
Yes, bad ground can cause serious dimming.
Why do my lights randomly dim?
Sometimes lights flicker and dim because of a loose bulb or a loose connection in the fixture. Lights in an entire room can flicker for the same reason that they go dim. They're on the same circuit as a large appliance, and the extra power drawn by the appliance when it cycles on causes voltage fluctuations.
