I have 3 wires wire 1 is my light , wire 2 is 12v to power the light and wire 3 is another 12v to power the light but in pulses . So I m thinking i would wire # 2 on # 1 then something that will block power to come back through to wire # 2 , then wire # 3 . So when i activate wire # 2 lite comes on , then when i activate wire # 3 it overrides wire # 2 and does the pulse . There are 2 lights and when i wired it up and activated wire # 3 it made both lights pulse and that is my problem i do nt want the current to go back through wire # 2 to the other light .
