I have been replacing the overhead light bulbs from incandescent to LED. I installed two over the sink, one incorrectly. They have a + - .The first I installed correctly, the second did not light, when I rotated the bulb the first one dimmed then went out. I put the old bulbs back and nothing, I checked the light over the sofa it is dead also. For the life of me I cannot find the fuse, not in the two panels under the bed, Not in the fuse box in the basement, or at least I didn't see a blown fuse.
