Aqua Signal Bi-Color, Tri-Color Bow & Steaming Lights

Aqua Signal Bi-Color, Tri-Color Bow & Steaming Lights

Aqua Signal carries a legacy that stretches back to 1868, when the company was founded in Bremen, Germany with a singular focus: marine navigation lighting. That depth of expertise is evident in every bi-color, tri-color, and steaming light the brand produces today. Whether you're running a powerboat at night or sailing offshore, Aqua Signal lights are engineered to keep you visible and compliant on the water.

Why Bi-Color, Tri-Color & Steaming Lights Matter

Navigation lights aren't optional equipment — they're a legal requirement and a critical safety tool. Bi-color, tri-color bow, and steaming lights serve distinct roles aboard a vessel. A bi-color bow light combines the red (port) and green (starboard) sectors into a single compact fixture, ideal for smaller sailboats and powerboats. A tri-color masthead light adds a white stern arc to those two sectors, allowing a sailboat under sail to display all required running lights from a single mast-mounted unit — saving power and improving visibility aloft. Steaming lights (white masthead lights used under power) round out the combination, letting other mariners read your vessel's heading and status at a glance.

Aqua Signal's Approach to This Category

Series 24 Hideaway Bi-Color Light: One of Aqua Signal's most distinctive offerings in this category is the Series 24 Hideaway — a stainless steel flip-up bi-color deck mount that keeps forward decks clean and uncluttered. It operates on 12V, features a built-in tell-tale indicator, and meets USCG (A-16) 2-mile visibility requirements for vessels up to 65 feet (20 meters).

Series 34 Tri-Color LED Masthead Light: Aqua Signal's Series 34 is purpose-built for sailing boats and features the latest LED generation in a slim, low-profile design. It is totally maintenance-free, operates on 12V or 24V, and delivers 2 nautical miles of visibility across its red, green, and white sectors. The Series 34 fulfills all requirements of the International Regulations for Preventing Collision at Sea 1972 (COLREG), as published by the IMO, and is available for all markets worldwide.

Series 40 Bi-Color Navigation Light: The Series 40 is widely regarded as an industry benchmark. Its patented design is built for sail or power vessels up to 65 feet and uses a rigid acrylic Fresnel lens that is both shock-resistant and seawater-resistant. The housing is rigid black polycarbonate — non-corrosive, non-magnetic, and shielded with stainless steel side shields. The Series 40 also supports the Quicfits mounting system for tool-free removal and re-installation.

Series 41 Bi-Color Bulkhead Mount: For boaters who prefer a bulkhead-mounted bi-color solution, the Series 41 provides a rugged, low-profile alternative that integrates cleanly into a vessel's deck or cabin structure.

Built for the Marine Environment

Across all its navigation light series, Aqua Signal prioritizes construction quality suited to the harshest conditions at sea. Housings are manufactured from glass-reinforced polycarbonate that is non-corrosive, non-magnetic, and seawater-resistant, while lenses are crafted from high-impact, shock-resistant plastic. Aqua Signal was also among the first marine manufacturers to release a comprehensive line of LED navigation lights, offering boaters significantly lower power draw — a meaningful advantage for battery-dependent sailboats — combined with extended service life and reduced maintenance intervals. All models are designed to meet USCG minimum visibility requirements and align with COLREG sector angles and chromaticity standards.
