My AF 1140 came thru with regular incandescents. They were the typical cheap ones with the removable cover. One of the first things I did was replace all of them with sealed LEDs from www.ledtrailerlights.com. Two of the incandescents already had water inside the covers when I removed them, and the TC was about 2 months old. Once enough water builds up inside the light, guess where it goes? Did you ever see the big wire access hole that is behind each light on an AF? Sealed LEDS cant leak as long as you have them installed properly and caulked well. Im going on 4 years now with the same LEDs and never had one go out. I think a lot depends on the quality of the light.
