When we had the boat
built I installed an Orca Green Tricolor... It is an LED, Anchor/Tri-Color and White Flashing Light.
I have no preference on the make of Light, but would suggest you find one that has a WHITE FLASHING LIGHT.
When we were cruising, I found the White Flashing Light invaluable in crowded anchorages
when friends are looking for you. A number of times I turned on the white flashing light for boats looking for the anchorage as well. Obviously in an emergency
, a white flashing light would work as a great visual aid.
To make sure it wasn't turned on accidentally, I wired the Flashing Light to come on only when both the anchor
switch and tricolor switch are on together.
I also don't think the Photocell on an LED Light is worth the price
since even if you leave the light on, you are only drawing about 1/10 of an amp.
