Partsam Blue 2-Pack 6-LED Underwater/Transom Boat Lights — 12V, IP68 Stainless Steel, 300+ Lumens

Partsam 2-pack blue 6-LED marine lights are stainless-steel, IP68-rated transom/underwater fixtures that deliver bright blue illumination for yachts, pontoons, and sailboats.

These compact 12V marine lights combine a 316-grade stainless-steel housing, a clear polycarbonate lens and six high-output LEDs to create a durable accent or underwater glow for recreational and small commercial vessels. Designed for surface mounting on the transom or hull, the pair arrives with long leads and sealed circuitry so you can add low-profile blue lighting without compromising seaworthiness.

How bright are these lights and what can they be used for?

The two lights each produce more than 300 lumens of single-color blue light, strong enough for underwater accent, transom illumination, or dock-side courtesy lighting. They are optimized to add visibility and atmosphere rather than replace navigation or floodlights.

• Six high-output LEDs per fixture provide concentrated color and consistent output.
• Suitable as underwater, transom, courtesy, or dock lights.
• Delivers uniform blue illumination for night-time aesthetics and visibility.

Will these hold up to saltwater and boat use?

Yes — the fixtures use 316 marine-grade stainless steel and a sealed circuit board under an IP68 waterproof rating, making them resistant to seawater corrosion and long-term immersion. The clear polycarbonate lens is chosen for impact resistance and light transmission in marine conditions.

• 316-grade stainless-steel resists rust and galvanic corrosion.
• IP68 sealing protects electronics from continuous submersion.
• Clear PC lens maximizes light output while standing up to marine wear.

How are these lights installed, and what wiring is needed?

Installation is surface-mount and requires a small through-hole for wiring; each light includes a 55-inch lead (red = positive, black = ground). For best performance, mount the lights low on the transom, roughly three inches above the hull bottom, and ensure the interior transom area is clear before passing the cable.

• Only a 3/5" hole required to pass the wire through the transom.
• 55" long wires are supplied to reach power sources behind the transom.
• Vessel must be hauled out of the water for proper installation.

What boats are these lights compatible with and where should they be placed?

The compact size and robust construction suit small to mid-size boats including center consoles, sport fishers, cruisers and wakeboard boats. Place each fixture at the lowest practical transom point for best underwater diffusion and appearance.

• Works with yachts, sailboats, pontoons, and similar vessels.
• Ideal for accenting swim platforms, transoms, or near boarding areas.
• Can be added in pairs to achieve balanced illumination across the stern.

Who this is for: Boaters who want a rugged, low-profile way to add blue accent or underwater lighting to small and mid-size vessels will appreciate this Partsam 2-pack. It’s intended for owners who need marine-grade materials and a fully sealed IP68 light for regular saltwater exposure, plus a straightforward surface-mount installation with long leads included. Avoid using these as primary navigation lights; they are designed for accent and underwater illumination to improve night-time visibility around the stern and dock areas.
