Expert Reply:
The lights you mentioned on your horse trailer are typically powered by the 12 volt power circuit of your trailer wiring. Since you said you have a Chevy Silverado it's most likely due to the fact that circuit isn't always completed. You can complete it by making a few connections under the hood of the truck.
I attached two FAQ articles to this page that detail how to make these connections. Since I don't know what year your truck is you'll need to pick the one that matches the year range of your truck.
