The light fixture in my bathroom has two lights; one on either side of the mirror. One bulb burnt out and I waited a week or 2 and the opther one burnt out. I had just one bulb and installed it in one side and it worked for a few weeks. IT then would sometimes flash byut not turn on when turning the switch on. I replaced both bulbs and they only dimly flash for a moment but will not turn on. What should I check ?
