Please measure your original bulb length before purchasing. If your stock bulb is 31mm, these can be used as direct replacements. **Q: Q2: What voltage do these marine LED bulbs work with?** A: A: These bulbs are designed for DC 12V systems. They are commonly used for boat anchor lights, masthead lights, stern lights, bow lights, all-round lights and running lights. **Q: Q3: What should I do if the bulb does not light up after installation?** A: A: Please remove the bulb, flip it 180 degrees, and reinstall it. These LED festoon bulbs are polarity sensitive, so reversing the direction usually solves the issue. **Q: Q4: Are these bulbs bright enough for boat navigation lights?** A: A: Yes. Each bulb uses 24 pieces of 3014 SMD LED chips and produces 6500K pure white light with up to 300 lumens. Please make sure your fixture and local boating requirements are compatible with LED replacement bulbs. **Q: Q5: Is installation difficult? Do I need extra wiring?** A: A: No extra wiring or modification is needed. These are plug-and-play direct replacement bulbs. Simply remove the old 31mm festoon bulb and install the new LED bulb. ## Customer Reviews ### ⭐⭐⭐ All around white, good. side light, not good. *by N***R on Reviewed in the United States on 7 July 2019* I was going to post a picture of them installed, but it really doesn't come across in a picture. For those asking if it looks blue/turquoise on the green lens, it doesn't. It looks green.But, the concentration of the white and bright seems to overpower the colored perko 963 lens. The bulb fit fine, had no issue with having to adjust or force anything. But the light is very concentrated and as you gain distance from it behind the lens, it sort of starts to wash out to white. I walked about 300 feet away and it became difficult to distinguish between green and white.I think it would work well as an all-around white light, but my all-around doesn't take a festoon. As it is, I'm not going to run these for my side lights. I don't trust that from a distance of a mile they'd look anything like another white light. ### ⭐ Poor Design - Will Blow Fuse *by F***. on Reviewed in the United States on 15 March 2020* Poor Design - Will Blow Fuse if your light housings' clips slide over the plastic ring and touch casing. Really cheap design and I blew 4 fuses before I realized the issue. Ended up buying LED's from Auto Parts store for like a buck more. ### ⭐⭐⭐⭐⭐ Perfect for my navigation light. *by S***E on Reviewed in the United States on 15 November 2019* I purchased this bulb to replace the incandescent bulb in my boat's red/green navigation light. Not only is it a perfect fit but brighter and uses less power, an important factor on boats. ## Frequently Bought Together - Shangyuan 31mm Marine LED Festoon Bulb for Navigation Light, Boat Light Bulbs for Boat Anchor Light, Boat Navigation Lights, Mast Masthead Light, Super Bright 12 Volt Bulbs for Boat Lights 2PCS - 906 LED 3Watt Bulbs T10 Wedge Base Marine Boat Light Bulb, 6000K White 12V 24V Navigation Lights for Anchor Light Stern Light All-Round Light Mast Masthead Light Pontoon Boat Sailboat Kayak 2PCS --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/280154635-31mm-marine-led-festoon-bulbs-for-navigation-boat-anchor-mast](https://www.desertcart.sn/products/280154635-31mm-marine-led-festoon-bulbs-for-navigation-boat-anchor-mast) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-07*
