HUSUKU 3in 18-LED Marine Courtesy Light White, 1200LM, IP65 SUS316 Bezel

The HUSUKU 3" 18-LED marine courtesy light is a compact, IP65 waterproof boat light that delivers 1,200 lumens of white illumination for interior and exterior marine use.

Built with a SUS316 stainless-steel bezel, a reinforced PC inner shell and a copper-conductive PCB, this 3-inch courtesy light balances corrosion resistance with high output. Its 120° beam spread and 1.5 m cable make it suitable for salon, cockpit, deck, transom and RV locations where reliable, low-profile lighting is needed. The pair of fixtures comes prewired and includes two mounting screws per light; note the recessed rear bulge requires a compatible mounting cutout rather than a surface mount.

How bright is this light and what kind of beam does it produce?

The HUSUKU unit produces approximately 1200 lumens from 18 LEDs for a bright, even wash of white light. The 120° beam angle provides wide coverage, reducing hot spots and offering usable illumination for tasks and general courtesy lighting on board.

• Output: ~1200 LM total from 18 LEDs
• Beam angle: 120° wide flood for even area lighting
• Color: clean white (suitable for visibility without harsh glare)
• Application: interior cabins, cockpits, decks, consoles, and steps

Is it durable enough for saltwater and outdoor use?

Yes — the trim is manufactured from SUS316 stainless steel, prized for marine corrosion resistance, while the inner housing uses high-strength PC plastic. The assembly is IP65-rated, protecting the electronics from jets of water and spray commonly encountered on boats and RVs.

• Bezel: SUS316 stainless steel for saltwater durability
• Inner body: impact-resistant PC plastic
• Seal rating: IP65 splash and spray protection
• Quality PCB: copper-conductive board with full soldering tin

How do I install the HUSUKU 3" marine courtesy light?

Installation requires a cutout that accommodates the 0.28-inch rear bulge — this is not a surface-mount fixture. The kit includes two screws per light to secure the bezel; always wire the lamp with an appropriate inline fuse per marine electrical codes for safety.

• Mount: requires recessed cutout for rear bulge (not surface mount)
• Cable: ~1.5 m pre-attached lead for easier routing
• Hardware: 2 screws included per light for firm fastening
• Safety: install with recommended fuse per boat electrical standards

What sizes, quantities and warranties are included?
