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:

    Easy to install and good, bright light. I installed these a few years ago, and one failed, due to water seepage into the unit. Attwood immediately replaced it free of charge. The wires are much smaller than on the boat, and so use a step-down butt connector.

      Comments about 3500 Series LED Navigation Lights:

      It's shocking that a company such as West Marine would continue to sell such junk, especially after SO MANY BAD REVIEWS. What gives, this is a must have product in the marine industry, and they don't last.
      Rather than replace the Port light with another under warranty, I'm thinking i'll be better off replacing the pair with another brand.

              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?

                      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.

                        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....
