Okay, I did not have time to look at this today, but thought I would post it here and see if someone has a quick answer. When I was checking my trailer lights after pulling the boat out today, I noticed that neither of my red lights on the rear of both wheel covers was lit, yet all other marker lights and taillights worked. Any ideas besides possibly a simple loose wire which I am hoping it is. I am asking in case it is not simple. Thanks in advance.
