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.

          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?
