Not required on a 12' boat, but I fish at night in a bay, so for safety I bought a bow light that I thought would last. The red light went out after less than a year. Upon inspection of failure, I can see where the led was not sealed correctly from factory, allowing h2o (and corrosion) into the led chamber causing failure. 10 yr warranty helps, but the 2 hr drive back to WM doesnt really make it worth it. Do not depend on this product. I guess I paid for the warranty, not a quality product as I had hoped.

    Nice look, poor reliability on port side. Factory regular lights give you more years of service than this expensive lights. Startboard still working. For how long?

        Corroded After 2 Years In The Tropics

          • Cheap Plastic
          • Not Weather Resistant
          • Poor Design

          Best Uses

            Comments about 3500 Series LED Navigation Lights:

            These might be okay for a trailerable boat that's covered all the time, but they do not last on an ocean-going cruising vessel. Cheap plastic construction with a stainless steel cover. Mine corroded after 2 years of summer torrential rains and slamming to weather in the tropics. Water entered into the "Closed LED" making them inoperable.

            Comments about 3500 Series LED Navigation Lights:

            I purchased the 3800 series stainless side lights. Thakfull West Marine has a good return policy.
            My review and ratings are my opinion and not good because it took a lot of effort just to make the bulb fit tightly. If you pay $44 each for a small plastic boat lights, you would expect to get marine quality. I have found better quality bulb fit in flashlights in the dolar store.
            These are nuch lower quality than a $24 universal trailer light system and you get both sides. Worse yet with the trailer lights you get everything and it will last at least 3 years. These will start coroding the first day.My life exptancy is 1 year. Never again.

              Comments about 3500 Series LED Navigation Lights:

              Apparently I have the earlier version, that appears to have the separate power supply and separate LED. Have now had to replace both port and starboard lamps....unexpected....thought these would last forever...
              The new version on port has gone 2 years, but in replacing the starboard one today, I note the wire is bare copper--not even marine wire once you get past the tinned end. If you put these on, be prepared to replace them. I got a warranty replace on the port, will do the same for the starboard and have a spare for both sides....

                This new LED bow light really updated and improved the bow area of my 31 year old sailboat. I plan to install similar units for the stern and mast lights.

                      In order to install, the lens cover must be removed to locate front mounting location. The lens covers do not come off easily. You are to turn the lens counter clockwise to remove. The factory says you need to push down and turn (not in instructions)On a 80 degree day I heated the lens, and only then was I able to remove the lens. The hole required is 1 1/8 to accept the bottom of the unit. I modified the bottom tab, so only a small hole is needed for the wires. Over designed without practicallity in mind.
