Here's a project we just finished this weekend. A friend recently acquired a B&O color position light signal. After getting it home, he dissembled, stripped and repainted the individual components. He then purchased items such as the base and mast necessary for installation. Over the past few weekends, we reassembled everything, installed the signal in the ground and rewired it. It is set up to display proper indications of clear, approach and stop in accordance with the rule book. It is indeed a very impressive addition to his yard.
Needless to say, we resisted the temptation to use a full height mast in his yard. The neighbors might not have liked that so much!
