What Are Underwater Lights?
Underwater lights are specialized marine-grade LED fixtures mounted below a boat’s waterline to illuminate the hull and surrounding water. These lights enhance nighttime visibility for navigation, docking, and swimming, while adding dramatic visual appeal that highlights the vessel’s design.
From megayachts and sailboats to tenders and sportfishers, underwater lights are also used to attract marine life, making them popular among anglers. DRSA’s underwater lighting systems, engineered with corrosion-resistant materials and advanced LED technology, are built for reliability and longevity even in the harshest marine environments.
Why Underwater Lights Matter
Underwater lights go beyond aesthetics; they provide real-world benefits for safety, performance, and enjoyment.
-
Night Fishing: Green and white LEDs attract microscopic plankton, which draw baitfish and predators closer to the boat.
-
Aesthetic Enhancement: Creates a stunning underwater glow that turns heads at marinas or anchorages.
-
Safety & Awareness: Improves visibility near docks, swimming zones, and shallow areas.
-
Durability: DRSA designs feature IP68 waterproofing and marine-grade materials for long-term reliability.

Types of Underwater Boat Lights
Surface-Mounted
Simple to install and cost-effective, these lights require only a small hole for wiring. Ideal for most hull types and smaller vessels.
Through-Hull or Flush-Mounted
Designed for larger boats and rough waters, these offer a secure, low-profile installation that integrates seamlessly into the hull.
Example in Context
“At 10:17 AM EDT on Friday, October 24, 2025, the tender’s DRSA underwater lights, set to green, attracted a school of fish for night fishing while casting a brilliant glow off the coast.”

Each DRSA underwater light is precision-engineered to handle saltwater environments with bronze or stainless steel housings and tempered glass lenses, ensuring clarity, strength, and style.
A Short History of Underwater Lighting
Underwater lighting began in the mid-20th century for industrial diving and marine maintenance. By the 1990s, advances in LED efficiency brought the technology into recreational boating. Today, color-changing systems like DRSA’s Lumishore and Lumitec models define the standard for both function and luxury.
Choosing the Right Light Color
Each color offers unique advantages depending on your goals:
| Color | Best For | Benefits |
|---|---|---|
| Green | Night fishing | Penetrates water best, attracts plankton and baitfish |
| White | General use | Bright, clear illumination for visibility and style |
| Blue | Saltwater | Performs well in open ocean with minimal scatter |
| Red | Shallow or calm water | Preserves night vision and attracts fewer insects |
Maintenance Tips
To keep underwater lights in top shape:
-
Rinse with fresh water after each outing to remove salt and debris.
-
Inspect lenses and seals for cracks or corrosion.
-
Secure wiring to prevent vibration-related wear.
-
Use DRSA-approved components for replacement and upgrades.
Professional servicing is recommended for through-hull installations to maintain waterproof integrity.
