Aurora 20 Inch LED Marine Series Light Bar Instruction Manual

1. Introduction

This manual provides essential information for the proper installation, operation, and maintenance of your Aurora 20 Inch LED Marine Series Light Bar. This high-intensity LED light bar is designed for marine and off-road vehicle applications, offering robust performance and durability in challenging environments.

The light bar features 40 high-intensity 5W LED chips, delivering a total of 200 watts of power and 17,120 lumens of 6000K bright white light. Its combo flood and spot beam pattern provides both broad illumination and focused light. Constructed with an IP69-rated 6063 aluminum housing, 316 stainless steel screws, and a UV and scratch-resistant lens, it is built for longevity and resistance to harsh conditions.

2. Safety Information

• Always disconnect power before installation or maintenance.
• Ensure proper wiring and fusing to prevent electrical overload. Refer to vehicle/vessel electrical specifications.
• Do not look directly into the light when it is operating, as it can cause eye strain or damage.
• Mount the light bar securely to prevent detachment during operation or movement.
• Keep wiring away from hot or moving parts.
• This product operates on a 10-30V DC power supply. Verify your power source compatibility.

4. Setup and Installation

4.1 Mounting

1. Identify a suitable mounting location on your vehicle or vessel. Ensure the surface is strong enough to support the light bar's weight and vibrations.
2. The light bar features flexible mounting brackets that allow for 360° rotation. Adjust the brackets to achieve the desired angle and position.
3. Mark the drilling points for the mounting hardware.
4. Drill pilot holes if necessary and securely attach the light bar using the provided hardware.

4.2 Wiring

1. Connect the light bar to the included wiring harness. The harness typically includes a relay, switch, and waterproof Deutsch connector.
2. Ensure all connections are secure and waterproof, especially the Deutsch connector.
3. Connect the positive (+) wire from the harness to a fused 10-30V DC power source. It is recommended to use a fuse appropriate for the light bar's 200W power consumption (approximately 16.7A at 12V, so a 20A or 25A fuse is advisable).
4. Connect the negative (-) wire from the harness to a suitable ground point on your vehicle or vessel.
5. Route the wiring safely, away from heat sources, sharp edges, and moving parts. Secure with cable ties.

5. Operating Instructions

Once installed and wired correctly, operate the light bar using the switch provided with the wiring harness. The light bar will emit a 6000K bright white light with a combo beam pattern, providing both a wide flood and a focused spot illumination.

6. Maintenance

• Cleaning: Periodically clean the lens with a soft cloth and mild soap and water. Avoid abrasive cleaners that could scratch the UV-resistant lens.
• Inspection: Regularly check all mounting hardware and electrical connections for tightness and corrosion, especially in marine environments.
• Breather: The light bar is equipped with a Military Aurora Patented breather designed to maintain waterproof integrity and air balance. No user maintenance is typically required for this component.
• Housing: The 6063 aluminum housing and 316 stainless steel screws are designed for corrosion resistance. Rinse with fresh water after exposure to saltwater.

7. Troubleshooting

• Light Bar Does Not Turn On:
  • Check all electrical connections for proper contact.
  • Verify the power source is supplying 10-30V DC.
  • Inspect the fuse in the wiring harness. Replace if blown with a fuse of the correct amperage.
  • Ensure the switch is functioning correctly.
• Light Output is Dim or Flickering:
  • Check for loose connections or inadequate grounding.
  • Verify the voltage at the light bar is within the 10-30V DC range. Low voltage can cause dimming.
• Moisture Inside Lens:
  • While the light bar is IP69 rated, extreme temperature changes can sometimes cause condensation. This usually dissipates with use. If persistent, inspect the housing for damage or improper sealing.
