I'm not sure if you are still available. Why are there 4 amber when a tree only has 3? there should be 2 sets of 2. there should be 2 sets at the top, pre-stage and stage. Some trees have a 2 for each lane facing diver and 2 for each lane facing down track to spectators. Another addition would be sensors on the track to light staging lights.
