Finally, a replacement miniature BA9S bayonet base LED for replacing the 20W halogen foredeck bulb found in the Aqua Signal Series 25 masthead/foredeck combination lights.

This LED bulb is a direct replacement for Aqua Signal 90470-7 and the Perko 0068 (006812V20W) 20W halogen miniature bayonet bulb.

Up until recently, a replacement bulb for these fixtures just wasn’t possible because of the small amount of room available in the fixture, plus the output and heat dissipation required to match up to a 20W halogen deck light. Thanks to CREE corp., in Durham, NC, we now have 5W emitters capable of such feats.

This 5W CREE Power LED, along with our driver electronics, are encased in an aluminum heat sink, which allow for a high power LED light without the damaging effects of heat. A small focusing lens on the end of the bulb protects the emitter from the elements, and focuses the light into a tight 30° spot beam to light up the deck.

This bulb has a 5W LED that we drive at about 2W. While this itself gives the bulb an effective light output (or equivalency) of about 15W, the additional bump in light output required comes from 100% of the light being collected and focused via a parabolic projection lens. This eliminated the need for your reflector, which is a good thing, as the reflective capability of most Aqua Signal reflectors last only a few months at sea.

A great LED at about the same price as the original halogen.

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.

Check fit before ordering

  • Function and sector: match the required anchor, steaming, stern, port/starboard, bi-color, or tri-color function.
  • Required performance: confirm the certification and visibility distance required for your vessel; brightness alone does not establish compliance.
  • Physical fit: compare the mounting footprint, fastener pattern, lens orientation, and available clearance.
  • Electrical fit: verify DC voltage, wiring, polarity, switching, and any photocell or multi-mode behavior.
