Perko LED Combination Masthead/ Anchor Lights 12V Converter Module. Wiring Note: Because direct wire-to-wire substitution of an older style incandescent light with this new style L.E.D. light will not work there are two installation alternatives: Rewire the existing switch to match the diagram supplied in the L.E.D. light instructions or Use the optional converter module (Cat. No 1680DP012V) and follow the wiring in the instructions provided with the new L.E.D. light so that no rewiring of the switch is necessary.
