Our 12V Wall Mount Pool and spa Light works on both AC or DC systems and both the brown and blue wires on the light are interchangeable. The two wires from the light will go to the two 12V output wires on the transformer. The two 120V input wires from the transformer (not included) will go to your light switch running the pool or spa light or the junction box. For detailed installation instructions for all types of our pool and spa lights, please click on the "instructions" link on our webpage.
