I have some ceiling mount fixtures in a closet and the light bulbs keep unscrewing from the vibration in the laundry room above it. The bulbs take some time to unscrew but eventually do. Is there anything I can try to stop this from occuring?
Carefully, set the bulb so the threaded end is on something solid but not the glass , take a screwdriver and put it across the thread of the bulb and tap it with a hammer so it is slightly deformed do this in a couple of places. It will be a little hard to screw in but it will stay in.
