How do you change a light bulb?

Answer 1

You simply turn off the light switch ( so you don't get zapped). Wait a minute or so for the bulb to cool, then unscrew the burnt out light and reinsert a working light bulb. Be sure to tighten the bulb (so that it makes good contact with the base) , but don't force it or over-tighten.
Turn the light off 1st to make sure you don't electrocute yourself, make sure to test the light after that.

Put it in and screw it clockwise. Yes, simple.

In a clockwise direction, until you can't screw anymore.

Caution: If you screw it in too much or too hard, it might break.
