Light Fixtures Not Working

When replacing light bulbs, make sure you use one that is in working condition. Light bulb elements are very thin and can easily be damaged either by dropping, shipping or transferring from the store. You can use a lamp that you know is working to test in in place of the light that is not working. New light bulbs sometimes are higher on the bottom of the lamp and when you install into the lighting fixture can cause the middle inside center prong to be lowered. When you install the new light bulb, if the base is shorter it will not make connection and will not allow the connection to be completed and the light to operate. If you have a dimmer controlling this fixture, you could have shorted out the dimmer and it needs to be replaced by a licensed electrical contractor.
