I just installed a new lighting fixture to replace an old one. The house was built in the 1990s so the wiring is not too old. The light fixture held two light bulbs and one was not working, so I replaced it. When I put the new one in, the same problem was happening. One light would work, and the other would not. I looked over the light and the wiring multiple times, but I am at a loss. Any suggestions?

Did you check to make sure both light bulbs were good?

Fixture wiring has to be defective. Can you show us a picture or drawing of fixture?

Yes the light bulbs were good I will try and post a picture later this evening I am going to try and take down the fixture and put a different one up to see if I have the same problem
