This combination tri-color / all-around anchor navigation light for sailboats is a great and economical LED solution to freshening up the top of your mast. The tri-color's LEDs lower the wattage by 80% while providing a brighter output than traditional 25W incandescent stack lights.
Why add a tri-color?
It substantially increases the distance at which your boat can be seen at night. Under the USCG/COLREG rules, a tri-color is optional while under sail, and provides a significant benefit in terms of visibility when cruising. It is highly recommended for cruisers and folks who venture offshore at night.
What is included?
Included is the tri-color/anchor stack light pre-fitted with replaceable Marinebeam LED bulbs. Up top is a partitioned tri-color LED bulb, and a 360 degree LED anchor light bulb. The bulbs are wired separately, and are controlled by using a single-pole-double-throw (SPDT) type switch (not included). A photocell anchor light is optional.
What is the photocell option?
The photocell option allows automatic dusk-to-dawn operation, which give you the flexibility to leave the boat in the daytime with the assurance that the anchor light will come on automatically at dusjk as the sun sets. It also automatically turns off the anchor light at dawn, so you don't need to remember to do it. This is all accomplished with the addition of a photocell sensor on the anchor light LED. The dusk-to-dawn function is enabled only for the anchor light. The tri-color is still switched manually.

The tri-color light blends together rather than form distinct color changes at 112.5°, 112.5°, and 135°. I had to make a blind on the inside of the light fixture to keep the colors separate, and a blind for the outside to make the color changes more distinctive.
The photocell on the anchor light only works when the sun is low on the horizon, otherwise the tri-color light blocks the photocell and causes the anchor light to turn back on.
