Xyanmc 31mm Marine LED Festoon Bulb Replacement 2-Pack
Best for: small boats, kayaks, and pontoon applications requiring compact, bright lighting with easy installation. This bulb features a heat-dissipation aluminum tube and 360-degree light, reducing hot spots and extending brightness life. It mirrors halogen form factor for compatibility with existing housings and uses a two-way lighting design that works non-polarity for plug-and-play setup. Ideal for masthead, bow, or stern lighting in compact boats where space is at a premium.
Why selected: It combines high lumens (200 lm) with low power (1.5 W) and improved durability through a PC lampshade and sealed design. The built-in heat sink helps maintain brightness during extended use, and the non-polarity feature simplifies the installation. A practical choice when you want bright, reliable light without rewiring a system.
Caution: Confirm your fixture size matches 31 mm before purchase; while designed to restore 1:1 halogen form, some older housings may still require adaptation.

Buying Guide
What should you ask before buying marine LED navigation bulbs?
- What is your boat’s electrical system voltage range? Look for bulbs rated for AC/DC 12–24V to cover most marine applications.
- What base does your fixture require? Common bases include BA15D, BA15S, T10 wedge, and festoon 31 mm. Match base and size to avoid fit issues.
- Is brightness and beam angle suitable for your needs? Higher lumens help in daylight conditions; 360-degree lighting avoids dark spots on decks.
- What is the expected lifespan? Longer lifespans reduce maintenance and bulb replacement frequency on boats away from shore.
- Do you need energy efficiency for battery-powered boats? Lower wattage with adequate lumens improves endurance during long outings.
