Combo Deck/Steaming light
Hello,
I just finished what you are starting. I had the Aqua signal series 25 and was ready to put it in place when I noticed that the connections were not well protected and the deck bulb was open to the elements. I looked at the Aqua signal 41 but decided it was too big for my mast. O'day 27' .
I returned it and got the Forespare model.

Much more robust connection wires and rubber grommet. The deck light is enclosed and both bulbs are very easy to swap out. I got the aluminum chafe guard and pop riveted it and the light into place (my new favorite tool). It was really easy to connect and install. Finished the wiring last weekend and it works like a charm. Very bright deck light and the steaming light is clear as day. I'm very pleased.
Couple of tips. You need 3 wires for the install. 1 neg and 2 pos. I used 14/3 ancor Bilge wire as it was the only 14/3 I could find. Ancor makes a 14/3 round white but I couldn't find any and didn't want to buy 100'. Wanted 14 guage because of the length of the run to and from the panel. It is ugly grey but easy to work with to get into the cabin. Once in the cabin I connected to other wires.
I used a cable clam to run the wires through the top of the deck. The cable clam was easy to install too.
Good luck.
