The lightbulb could be burning out. The lightbulb could also be loose in the socket. What is the brand and model of your garage door opener?
When I called local business, a man told me it comes apart (ceiling fixture with light) by either sliding up or down. Have been up on a ladder several times = cannot get loose. I'm afraid of breaking it. Service call = $115 !!! Can anyone help me? Thanks for any suggestions
