I have an outdoor light at my house that receives power at random and
then the light goes on; it also loses power out at random. There is no
way to turn it off except to unscrew the bulb. Are there any
suggestions as to what it may be? I have a multimeter and know how to
use it.


This situation could cause a fire. Turn off the circuit at the main.
Check to make sure the circuit has no power. Remove the lamp and
check for corrosion. Remove the lamp base and check all the wire
nuts. Chances are one is loose. If you find all connections are
tight, move your way back to every electrical box on the circuit and
check the nuts there too. A loose wire can cause arcing so after you
remove the lamp base inspect the interior with a flashlight for any
black marks.
