What Is Surface-Mounted?
Surface-mounted refers to a straightforward lighting installation method in which fixtures are attached externally to the boat’s hull, transom, or deck, typically using brackets, marine adhesives, or screws, without drilling a full-through hole. This design keeps the vessel watertight while offering quick, clean installation and easy maintenance.
It’s especially popular for underwater, courtesy, and deck lighting, providing a secure, low-profile fit ideal for retrofitting or upgrading older vessels. DRSA’s surface-mounted lights, engineered from marine-grade materials, deliver superior corrosion resistance, waterproof performance, and long-term reliability in saltwater environments.
Why Surface-Mounted Lighting Matters
Surface-mounted installations balance simplicity with strength, making them one of the most practical solutions for marine lighting.
-
Ease of Installation: Minimal drilling, tools, and downtime perfect for quick retrofits.
-
Cost-Effectiveness: Less labor and fewer materials than through-hull systems.
-
Versatility: Works across hulls, transoms, or docks on tenders, sailboats, and megayachts.
-
Durability: DRSA’s IP68-rated lights withstand saltwater, vibration, and pressure without compromising aesthetics.

Understanding Surface-Mounted Design
Surface-mounted lighting is favored for its simplicity and watertight integrity. Unlike through-hull installations that require cutting larger holes in the hull, surface-mount lights only need a wiring entry point. This makes them ideal for vessels that prioritize quick installation or retrofitting existing boats.
DRSA’s models, such as the Zambezi series, feature marine-grade stainless steel housings, tempered glass lenses, and energy-efficient LEDs that consume up to 90% less power than traditional lighting systems.
A Brief History
The surface-mount concept originated with early waterproof exterior fixtures in the mid-20th century. As marine lighting evolved, the introduction of LED technology in the 1990s made compact, efficient, and low-heat designs possible.
By 2025, DRSA’s Zambezi and Javelin series have defined the standard for high-output surface-mounted underwater lights, offering the performance of through-hull systems without the complexity.

Maintenance Tips
To extend the life of your surface-mounted lights:
-
Rinse with fresh water after each use to prevent salt buildup.
-
Inspect mounts and wiring regularly for looseness or corrosion.
-
Check seals and lenses for cracks after long voyages.
-
Use DRSA replacement parts for compatible LED modules and drivers.
-
Reapply marine adhesive if mounting plates show signs of separation.
