Thinking about getting one of these to put on my new cafe seat I'm making. I had an old Evinrude cowling for a 4hp laying around and thought it would be perfect for a cafe seat back. I want to place a small round light and love the look of the Lucas l594 beehive light. Question is, how will this work with the three wires I have now as the Lucas only has 2? I figure that Id need a dual element bulb, but that is as far as my little brain go. Any suggestions?
