My flex-a-lites stopped working all of a sudden the other night. I think it might be a relay. There is a design and numbers on them, but they are so worn I can't tell what it says on any of them. I don't want to get the wrong ones and jack it up or anything. Thanks!

 

Common 5 prong automotive relay. I recommend Tyco or Bosch brands, 40 or 50 amp.
