Electrical Question: How do I fix an outdoor light that is not working right?

  • I have an outdoor light that is not working right.
  • First I wired a single pole switch to the light box and this is correct because I verified the wiring using another light fixture and it works just fine.
  • I replaced the light with new fixture and it will not work.
  • I know that the new light fixture works hard wired to an outlet, so the fixture works.
  • As you can tell, I am frustrated and would appreciate some assistance.

Any help would be great!
Additional Comments: I love what I see here, I have been looking for an hour for advise, this is where I stopped.

    • Locate the circuit breaker which provides power to the light switch and make sure it is not tripped.

      • Reset the circuit breaker.

  • Light Bulbs
    • Sometimes the wire filament inside the light bulb may be broken but when it is in certain positions it will make contact and light up, therefore a new bulb may be required.
    • Make sure the light bulb is the right size and type. For example: most CFL lamps do not work well in outdoor lights, however incandescent or halogen lamps generally work best. Be sure to check the light fixture specifications for specific lamp replacement information.
