HQRP BAY15d 24LED SMD5050 Cool White Light Bulb compatible with Aqua Signal Series 40, 41, 42,& 50 / Hella 2984 and Perko 200 Fixtures 10-30V DC Replacement

I just had the boat out for 6 months mostly at anchor. We never even turned it off during the day. It took very little power and was very bright. Highly recommended for the replacement anchor lamp.

These fit perfect for Perko navigation lighting. other BAY15d bulbs didn't seat right. I had issues with others rated at 10v-30v. These are perfect in a 24vdc system. Pretty cool color on the spectrum but that is ok in my application.

I bought this to replace the bulb in the Hella stern light on my boat. Although the pins were the correct type for BAY15 this item would not fit into the recepticle. It completely broke into little piece when I tried to push it in and twist it into place. It is a waste of time and money.

This bulb perfectly replaces the incandescent bulb in my Aqua Signal 41 steaming light. It works with light's plastic socket. It has a negative and a positive contact on the bottom. It has offset locking pins to control polarity. It is well made and unlike the photo in the listing it has a clear plastic shell around it protecting the LEDs. There were not any blobs of solder affecting my installing the bulb into the socket. I have included a photo of this bulb next to the original incandescent bulb. I have used it 12 hours as of this review.

Works great but the manufacturing has a minor defect. The solder points were too thick around the bulb circular sleeve. It would not allow me to push the bulbs in deep enough into the housing socket, and therefore I was not able to twist slightly so it can snap into the final seating position. I had to take a solder gun and remove excess solders around the brim of the bulb. Once done, they seated fine. I had to do this to all 6 bulbs I had ordered. I had used them to replace all the old incandescent lights on my boat exterior markers and running lights. After 6+ months, none of these LED has failed from exposure and vibration. Which is pretty good as the locations where these bulbs are installed are very difficult to reach while the boat is in the water.
