Cause of On and Off Dusk to Dawn Light Fixture
Electrical Question #1: What would cause a dusk to dawn light fixture to turn on and off?
I have a dusk to dawn light fixture that turns on and off quite a lot. I replace an old outside light fixture with a new Area dusk to dawn fixture. I had observe that the new light fixture goes on and off. It come on about 5 min, then back on with 5 min., what could be the problem?
This electrical question came from: Bob, a Homeowner from Los Angeles, California.
Electrical Question #2:
- We have outdoor motion sensor light, I do not know where the off on switch is, and it is flicking on and off. I am afraid it may have frayed wiring and could cause a fire. How do we locate the correct switch?
This electrical question came from Tim in Cottageville, South Carolina.
Electrical Question #3:
I have a dusk to dawn motion light. It works just fine at night. Motion activates it and the light burns until the time expires. The problem is during the daytime. Once it becomes light outside the light comes on and burns until it detects dusk again. Once it becomes dark it works properly until the next morning.
This electrical wiring question came from Skip, a Handyman in Bedford, Indiana.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
