The Led lights from Home Depot come packaged two different ways. In a package with three LED lights and a 120 volt AC to 12 volt DC power supply or as single LED lights packs so that you can daisy chain to the lights to each other and the power supply to increase the number of lights. I bought three single light packs. The lights pucks have three super bright LED a long wire leads and connector to daisy chain the lights together. I removed the last lights puck connector and wired it to 12 volt wire from the old lights and covered the wires with a piece of teaks.
Thrifty, Bright, Low Power, and Best of all, the Admiral loves them!!!!!!!
