Introduction
This manual provides essential instructions for the proper installation, operation, and maintenance of your SEACHOICE 05011 Bi-Color Bow Light. Please read these instructions thoroughly before installation and retain this manual for future reference. Correct installation and maintenance ensure optimal performance and compliance with navigation regulations.
Product Overview
The SEACHOICE 05011 is a bi-color bow light designed for marine navigation. It features a red light for the port (left) side and a green light for the starboard (right) side, providing 112.5 degrees of visibility for each color. This light is crucial for indicating the presence and direction of your vessel during periods of darkness or restricted visibility, adhering to international navigation rules.

This image displays the SEACHOICE 05011 Bi-Color Bow Light. The light features a chrome-plated top housing and a black base. The front portion shows the red (port) and green (starboard) lenses, which are essential for navigation.
Setup and Installation
Proper installation is critical for the functionality and legal compliance of your bow light.
Tools and Materials Required:
- Screwdriver (appropriate for mounting screws)
- Drill (if pre-drilling is necessary)
- Wire strippers/crimpers
- Marine-grade sealant
- Electrical tape or heat shrink tubing
- Appropriate gauge marine wire (if extending existing wiring)
Installation Steps:
- Select Mounting Location: The bow light must be mounted at the foremost part of the vessel, ensuring an unobstructed view of the red and green lights from the front and sides. The light should be positioned to provide 112.5 degrees of visibility for the red light on the port side and 112.5 degrees for the green light on the starboard side.
- Prepare Mounting Surface: Ensure the mounting surface is flat, clean, and structurally sound. If necessary, pre-drill pilot holes for the mounting screws, taking care not to drill through critical components.
- Wiring Connections: Connect the light's positive wire (typically red) to the vessel's 12V DC positive power source, usually through a switch on the electrical panel. Connect the negative wire (typically black) to the vessel's common ground. Ensure all electrical connections are secure, corrosion-resistant, and properly insulated using marine-grade connectors, electrical tape, or heat shrink tubing.
- Mount the Light: Secure the light to the prepared surface using the provided mounting screws. Apply marine-grade sealant around the base of the light and screw holes to prevent water intrusion.
- Test Functionality: Once installed, activate the light switch to confirm both the red and green lights illuminate correctly. Verify that the light is securely mounted and that all wiring is tidy and protected.
Operating Instructions
The SEACHOICE 05011 Bi-Color Bow Light is designed for straightforward operation as part of your vessel's electrical system.
- Activation: Turn on the bow light using the designated switch on your boat's electrical panel.
- Usage: This light must be used during periods of darkness (from sunset to sunrise) and during restricted visibility conditions (fog, rain, etc.) to comply with maritime navigation rules.
- Visibility: Ensure the light is always clear of obstructions to maintain maximum visibility for other vessels.
Maintenance
Regular maintenance will prolong the life and ensure the reliability of your bow light.
- Cleaning: Periodically clean the light's lenses and housing with fresh water and a mild, non-abrasive soap. Rinse thoroughly to remove any salt residue or dirt. Avoid harsh chemicals that could damage the chrome finish or plastic lenses.
- Inspection: Regularly inspect the light for any signs of corrosion, especially on electrical connections. Check for loose mounting screws or cracks in the housing or lenses.
- Wiring: Ensure all wiring connections remain tight and free from corrosion. Apply dielectric grease to connections if operating in harsh marine environments.
- Bulb Replacement (if applicable): If the light uses a replaceable bulb, refer to the bulb manufacturer's specifications for replacement. Ensure the replacement bulb matches the original type and wattage. If it is a sealed LED unit, the entire unit may need replacement if the light fails.
Troubleshooting
If your SEACHOICE 05011 Bi-Color Bow Light is not functioning as expected, consider the following:
- Light Does Not Illuminate:
- Check the vessel's electrical panel for a tripped breaker or blown fuse.
- Verify that the light switch is in the 'ON' position.
- Inspect all wiring connections for looseness or corrosion.
- If applicable, check the bulb for a broken filament and replace if necessary.
- Light is Dim or Flickering:
- Check for low voltage at the light fixture. This could indicate a poor connection or an issue with the vessel's power supply.
- Inspect for corrosion on the electrical contacts or wiring, which can impede current flow.
- Water Inside the Lens:
- This indicates a compromised seal. Disassemble the light carefully, dry the interior, and reassemble, ensuring all seals are properly seated and applying marine-grade sealant around the base during remounting.
