Wanted to post this in case someone else ever has this trouble. Was checking the lights on my trailer today. Everything worked except the tailights. Well as has been said before the 3 main causes of light issues is
1. Bad ground
2. Bad ground
3. Bad ground
So I start checking the grounds. I had a broken ground on the driver side light. Even though each light has it's own ground the passenger side wasn't even working and all the other light functions were. Like I said they are tricky little devils. So if you are having lighting issues ALWAYS check those grounds first thing.
