[Rhodes22-list] mast lighting

[cjlowe at sssnet.com]

Rob,
Give a little thought to how you are planning to use your boat. If you are
going to anchor out,you should have an anchor light. If you sail at night
(moonlight sail ) it would be nice to have a windex light. And if  you
sail at night, you really ought to be legally  able to motor at night.(
steaming light ) . If you anchor over night, it's nice to have a deck
light to put on the pop-top or check anchor rode,ect. If you run one pair
of wires up to the top of the mast,you can use that for the anchor and
windex light,if you use the double pole / double pole switch and LED
lights. If you use the steaming light wires to power a LED steaming light/
deck light combination unit , you will only need to change the switch. I
would advise you to not reuse old lights and just replace the bulbs with
led replacement units ,as you still have the clips that make the
electrical transfer of power that are a weak point in the circuit. If your
vhf antenna cable is getting lone in tooth,no would be a good time to
upgrade.

It worked for me,
Jerry Lowe
