Everything was fine for a year or so but now the brake lights are both malfunctioning (LED bulbs burned out and flickering of lights on braking).
Our repair shop called Command Electronics and they agreed to replace them both at no cost (except shipping costs which was fine with me).
All in all, I am happy with Command electronics customer service and am thankful they stood behind their product after almost two years of ownership. We pick our rig up next week.
That said, I was originally ready to ditch the factory lights and go with something that MIGHT be more dependable. The trouble with that is the holes for those factory LED LED lights are so large that many other lights will not fill the hole and still allow for securing them with screws (Most other styles are too small). In the end we just decided to replace both with the same Command Electronics lights and hope for the best.
You didn't use their supplied foam gaskets did you?
