Recently I had the taillight assembly replaced on our tow vehicle. At the same time I noticed that the brake controller light
was constantly on without towing the trailer. While talking with Casita
I mentioned this because I thought it might have something to do with the work on the tail light
. The response was that they did not think so and that this has happened to other vehicles. The thought is that the connection gets wet and shorts? out causing the light
to go on. This may be true since during that time we had a lot of rain. Today I plugged in the pigtail just to check out the trailer lights
and noticed that the controller light is no longer. Coincidence? Has anyone else had this experience? Thanks.
