Under NODS when there is no key in the ignition and the engine not running. I was out in the field tonight, turned around to walk back to the house and observed the flashing on and off on my trailer. I unplugged the pig tail and naturally it stopped but this cannot be seen without the PVS-14’s on. I am puzzled....
 
LED trailer lights? It takes very little energy to get enough to flash them. I have seen it before with my 2015 Ford F350 and my gooseneck trailer that we were using to hunt off of. I think it's part of the body control module checking the connection. Since the 4 way flashers and brake lights work no matter whether the key is in the ignition or not this could occur in any condition.
