Advice from real cruisers

These 31mm (1-1/4″) LED SMD festoons are excellent for replacing incandescent festoons in small courstey lights. These work great in the floor level courtesy lights found on the newer boats from Beneteau, and other yachts. The FS-31-04 will also fit in Perko 1100 Fig. 71 Port and Starboard Navigation Lights where the boat has separate red and green fixtures. If you have separate bow fixtures, choose red and green bulbs respectively to achieve near-perfect transmittance. For other Perko NAVIGATION AND ANCHOR LAMPS, see our Perko Selection Guide.

Shipping & lead times

We're a small team of boaters and we pack orders within 1–5 business days (no weekend or holiday packing). You'll get an email with tracking as soon as a label goes on your box.

Specialty items — fire extinguishers (dangerous goods) and low-stock or built-to-order gear — can take longer; the product description will say so. On a tight timeline or meeting your boat somewhere specific? Contact us and we’ll work out the fastest way to get gear to you.

International orders ship DDU: local duties, taxes, and customs fees are the buyer’s responsibility. Full details in our shipping policy.

Returns & refunds

30-day returns from the date of purchase. Items must be unused, in the original packaging with all cables and accessories, with proof of purchase.

Contact us before shipping anything back — we’ll send the return form that must accompany your return. Fire extinguisher and lithium battery items carry a $15 administrative fee on returns.

Read the full refund policy.

Ask a cruiser before you buy

Everyone here is a current or past cruiser — we’ve docked short-handed, re-rigged at anchor, and chased 12V gremlins too. Not sure this is the right fit for your boat? Send us your question before you order and we’ll give you a straight answer.
