Hello Bill, thanks for reaching out. Yes, the Replacement Reed Switch # DM65MV will indeed work with the Demco Air Force One Flat Tow Brake System for 2020 and Newer Tiffin Chassis RVs w/Factory Air Brakes # DM55MV. I have heard of the reed switch arcing to ground then either no longer working or staying on all the time so that could be the case here.

Hey Bill, how did things turn out with the replacement reed switch on your Air Force One brake system? Did swapping it fix the issue with the LED light staying on? Your update could make it easier for the next person with the same problem.
