BI- Color Bow Light

A bi-color bow light is a combined navigation light fixture that emits both red and green lights, typically installed on the bow (front) of smaller boats. It serves as a sidelight, indicating the vessel's port (left) and starboard (right) sides to other boats, similar to separate red and green sidelights, but in a single unit. 

Specification

Angle :   225°
Visibility :   2NM
Lumen:   10LM
Weight:   0.52kg
Height:   45mm W x 79mm H

Here's a more detailed explanation:

Purpose:

The primary purpose of a bi-color bow light is to provide visibility to other boats, helping to prevent collisions, especially at night or in low-visibility conditions. 

Placement:

It's mounted on the bow of the boat, as far forward as possible, to maximize its visibility from other vessels. 

Light Colors

The light emits a red light to the left (port side) and a green light to the right (starboard side). 

Visibility:

These lights are visible from 2 nautical miles away and cover an arc of 112.5 degrees on each side, creating a continuous arc of illumination from 112.5 degrees on the port side through dead ahead to 112.5 degrees on the starboard side. 

Regulations:

Bi-color bow lights are typically allowed for boats under 65 feet in length, according to Apex Lighting. 

BI- Color Bow Light 12V Small Boat

A bi-color bow light is a navigation light typically installed at the bow (front) of a small boat to help indicate its direction of travel to other vessels during low visibility conditions, such as at night or in fog.

Here's a more detailed explanation:

What is a Bi-Color Bow Light?

  • Red light on the port side (left when facing forward).

  • Green light on the starboard side (right when facing forward).

What is a Bi-Color Bow Light?

  • Red light on the port side (left when facing forward).

  • Green light on the starboard side (right when facing forward).

12V – What Does It Mean?

  • The 12V indicates that the light operates on a 12-volt electrical system, which is standard on most small boats.

  • It's typically powered by the boat’s battery and connected via a switch or control panel.

Purpose of the Bi-Color Light

  • Helps prevent collisions by signaling your boat’s orientation to others.

  • Complies with navigation rules (COLREGs – International Regulations for Preventing Collisions at Sea).

  • Required by law for boats operating at night or in low visibility in most regions.

Specification

Angle :   225°
Visibility :   1NM
Lumen:   5LM
Weight:   0.52kg
Height:   45mm W x 79mm H
Material: Chrome Plate-Zinc

Purpose of the Bi-Color Light

For most powered vessels under 12 meters (39.4 feet):

  • Must have red/green side lights (which a bi-color light covers).

  • Plus an all-round white light or a white stern + masthead light.

  • For sailboats under sail only, the bi-color light is also acceptable in some configurations.
