Bought a used 2008 Hannigan Sierra trailer and needed to replace the spoiler break light. Hannigan had it in stock and shipped it pronto. My question now though is are the front side running lights susposed to turn off when the brake lights come on? They also blink with the blinker it turned on which at first I thought wasn't right but I could see the purpose in that from the side traffic standpoint. Can someone shed a little "light" on this for me?
