My wife and I just moved into our first house. On our deck outside, there are 2 lights. One is a single bulb wall mounted and the other one are two flood lights. These are controlled by two indiviual switches on the wall right next to the sliding doors. They have been working fine until last night when I went to put them on, they both went out, like a bulb blew. I didnt honestly think all 3 bulbs could go at once, so I only tried changing one, which didnt work. I then thought maybe the switches were bad, so I changed them next( I was going to anyway)they are single pole, which I replaced them with single pole again. The breaker didnt pop either. The only thing that I did prior to that was I took the face plate off one of the wall sockets,but the outlet was a little loose. Could that be the problem? But, again the breaker didnt pop. Any help would be appreciated before I call in an electrician.
