Rod,
In reality you do not need to do anything but purchase the correct LED Bulbs. Go into the search mode and find the thread where years ago we talked about replacing all the standard bulbs in the 022, 072 and old 711 switches with LED's I can not remember the exact numbers on the LED's, however they are LED's with flat heads. These LED's work perfectly in both the track side fixture and the controllers. It is true some of the other different LED's have trouble in the controllers. In the thread you will find the exact numbers for the different LED's and where we were purchasing them.
