Partsam 3" Blue LED Marine Stern Lights 4-Pack — 12V Surface-Mount, IP67 Waterproof, Low-Draw SMD LEDs

Partsam 3-inch round blue LED transom stern lights are surface-mount, IP67 waterproof navigation and deck lights designed for 12V marine use, sold as a 4-piece set. These compact LED fixtures combine bright blue illumination with a low electrical draw and a corrosion-resistant bezel for use on sterns, swim platforms, decks, or inside cabins. Built to resist water intrusion and designed for straightforward surface installation, they replace older incandescent lights and add visible, energy-efficient lighting for night fishing, boarding, or ambient deck illumination.

How bright and efficient are these lights?

Each lamp uses high-efficiency SMD LED chips that deliver clear blue light while consuming minimal current, extending battery life during long nights on the water. They are optimized for visible deck and transom use rather than long-distance navigation beams.

• 3-inch diameter housing for concentrated illumination
• 12V DC operation compatible with standard boat systems
• SMD LEDs for low draw and long operating life

Will these hold up in marine conditions?

The fixtures are engineered with an electroplated plastic bezel and a durable polycarbonate lens to resist UV and impact. Rated IP67 for water protection, they withstand temporary immersion and splashes common at the stern or on swim platforms.

• Electroplated plastic flange reduces visible corrosion
• Clear PC lens resists cracking and weathering
• IP67 rating for dust protection and temporary immersion

How easy are they to install and replace existing lights?

These surface-mount lights come with the mounting screws needed for installation and are designed to replace bulkier incandescent stern or courtesy lights. They do not mount completely flush without a recessed pilot and sink hole for the housing, so plan for minor drilling if you want a flush finish.

• Includes mounting screws for quick installation
• Surface-mount design for vertical transoms and flat surfaces
• Tip: drill a pilot screw hole then a 1/2-inch sink hole for a flush fit

Can these be used inside the boat or for different purposes?

Yes — while intended for stern and deck lighting, the compact form and gentle blue hue make them suitable for cockpit courtesy lights, cabin compartment lighting, or accent illumination. They work wherever small, low-profile LED lighting is helpful, provided the 12V supply and mounting surface are compatible.

• Suitable for cockpit, cabin, swim platform, or deck accent lighting
• Works as a courtesy or compartment light with low heat output
• Compact 3-inch diameter fits many retrofit locations

Who is this for? Boat owners, anglers, and marine DIYers who want reliable, low-power blue lighting for sterns, swim platforms, decks, or interiors will find these Partsam fixtures useful. They suit people upgrading from incandescent lights to LEDs, those needing waterproof surface mounts for vertical transoms, and anyone seeking simple bolt-on lighting that blends durability with a compact profile.
