2017 Ford Focus Fiber Optic Tail Lights

I've had these lights now for around 2 months and have only had one issue where once when sitting in traffic waiting to make a left turn the indicators started flashing much much quicker than normal. Again it only happened once and hasn't happened since. I'm also a little concerned about the potential for condensation build-up within the assembly housing, I've seen a mild instance of this once now as well but it cleared up and hasn't become a pervasive issue yet.
