Definition of Combination Light
See Sidelight
A combination light is a navigation fixture that merges the red port light and green starboard light into a single, compact housing mounted on the centerline of a boat’s bow.
This single fixture provides the same directional visibility as individual sidelights, helping other vessels identify your heading and position at night or in low visibility.
Combination lights are approved only for boats under 65 feet (20 meters). Larger vessels must use separate port and starboard sidelights to comply with international navigation lighting standards.

Benefits of Combination Lights
Modern combination lights are primarily LED-based, offering several advantages for marine applications:
-
Brighter, more consistent illumination for improved visibility
-
Low power draw that conserves battery life
-
Long service life with minimal maintenance
-
Compact, lightweight design suited for small boats and sportfishing vessels
These fixtures improve safety and simplify installation, making them a top choice for boat builders and refit projects.

Frequently Asked Questions
What boats can use a combination light?
Combination lights are approved for vessels under 65 feet in length. Larger boats require separate sidelights to comply with navigation regulations.
Is this light waterproof?
