Take the 2-minute tour ×  I have an LED light bulb: Philips 60W
incandescent equivalent  I've owned it for about a year and have
been very happy with it. This morning when I turned it on, it
started blinking. Not flickering, but a very deliberate one
second on, one second off, one second on, one second off. This
continued until I fiddled with the bulb at which point it came
on and stayed on.  Its never done this before. I unscrewed the
bulb and it rattles. Something in it may be broken, but it still
seems to work. I couldn't find anything on the Philips website
about this type of behavior. Does anybody know what it means?

socket? I have had non-LED bulbs slowly unscrew themselves
untill they are only
