I have an interior flood light over the sink in my kitchen. I've lived in this house for 7 years, and have occassionally had to replace this light. Lately, however, when I replace the bulb, it burns out about a week later. We'll just be standing there in the kitchen, and we hear a snap sound, the light flashes, then goes dark. Not having this issue with any other lights in the house. Anybody have an idea of what's happening? Thanks!
