Yes, the Buyers Products LED Trailer Dome Light with Switch item # 3375625337 is sealed and would be perfect in a livestock trailer. The low-profile design of the light is only 5/8" thick so it won't hang down and run the risk of being broken. It has 36 LED diodes that last 50 times longer than incandescent lights. view full answer...
