Mast top Tri-color/Anchor light control

 

Mast top Tri-color/Anchor light control

This project fixes two problems 

1. Is using 2 wires to mast top to control combined Light instead of 3 when you upgrade just anchor light with combined 3-color/anchor light to use existing wires instead of replacing cable it mast top.
2. Control switching  between deck level side lights and tri-color when you motoring without adding additional switch to your breaker/switch panel. 

NOTE: BE SURE YOU NEVER SHOW tri-color on mast top and steaming light together it is prohibited by rules, you may confuse other boats showing just Red or Green on top of white. (it is what others will see in this case from bow side)

 How lights controlled after control board added.
