hi guys, i hooked my trailer up and checked the lights and found that when i turn on the r directional, both l and r directionally come on. i checked the trailer with another truck and it works fine with another vehicle. i did have a problem with the directionals about a month ago, when i put the rt turn signal on, the flashers would come on. it did it a few times and it hasn't done it since. thanks for any help you can give me.
