My AC 120v Panel Has a Light Which Is Green and Red. the Green Light Does Not Glow Bright and Steady - Is This Normal?

Question:

Hi Jeff, I have been watching your YouTube shows for the past few years and learned so much. My question is this. My AC 120V panel has a light which is green and red. I assume that the red is bad but the green light does not glow bright and steady on either shore power or generator power. Is this normal, a problem or just a bad bulb? - Eric

Answer:

The red light is to indicate the problem of reverse polarity. The green light means the AC breaker on the AC panel is energized. Yes, it's normal for the green light to burn out over time.
