Hello there. My name is***** and i'll be helping you with your light fixture problem. "The light works but only with 1 working bulb or the other", could you clear this up for me?
Are both fixtures doing the same thing?
Have you checked your connections, both black and white? Sometimes a loose wire can cause some funny problems. Also, check to make sure you have both bulbs screwed in snug but not tight.
No that doesn't make a difference. The other fixture you put up should have 2 white and 2 black coming from ceiling. Have you tried different bulbs? Sometimes you can get bulbs that are just bad that are new.
Sorry if these questions seem simple at first but, I have to get questions like these out of the way to troubleshoot further.
Also, I'd like to know, is this a fluorescent light fixture?
If you have checked everything I have stated above, try using the other light fixture in this ones place. This will tell us if there are loose wires in the fixture itself.
Leave the 2 additional wires alone. They are just feeding through the box. Be sure to check the white wires. Things like this can happen because of improper back feed. Also, I highly suggest having both fixtures installed then see if the problem consists.
Did any if this resolve your issue?
