5. Setup

1. Prepare Mounting Surface: Ensure the vehicle's roof or desired mounting area is clean, dry, and made of ferrous metal (iron). Remove any dirt, dust, or moisture that could affect magnetic adhesion.
2. Attach Strobe Light: Carefully place the magnetic base of the strobe light onto the prepared metal surface. The strong magnets will secure the light in place.
3. Connect Power: Plug the 12V cigarette lighter plug into your vehicle's cigarette lighter socket.

6. Operating Instructions

1. Power On/Off: Use the red power switch on the cigarette lighter plug to turn the strobe lights on or off.
2. Change Flash Patterns: Press the momentary switch (usually a black button next to the power switch) on the cigarette lighter plug to cycle through the 16 available flash patterns. The light will remember the last selected pattern when powered off and on again.

7. Maintenance

• Cleaning: Regularly clean the transparent housing and PC optic lens with a soft, damp cloth to maintain optimal brightness and visibility. Avoid abrasive cleaners.
• Magnetic Base Inspection: Periodically check the magnetic bases and protective rubber feet for wear or damage. Ensure the magnets are clean and free of debris to maintain strong adhesion.
• Cable Inspection: Inspect the power cord and cigarette lighter plug for any signs of damage, fraying, or loose connections.
• Storage: When not in use, store the strobe lights in a cool, dry place away from direct sunlight and extreme temperatures.

8. Troubleshooting

• Lights Not Turning On:
  • Check if the cigarette lighter plug is fully inserted into the vehicle's socket.
  • Verify the power switch on the plug is in the 'On' position.
  • Check the vehicle's fuse for the cigarette lighter socket.
  • Inspect the built-in fuse within the cigarette lighter plug and replace if necessary.
• Lights Detaching During Use:
  • Ensure the vehicle speed is below 40 mph (64 km/h).
  • Verify the mounting surface is clean, dry, and made of ferrous metal.
  • Check the magnetic bases for any debris or damage that might reduce adhesion.
• Inconsistent Flash Patterns:
  • Ensure the momentary switch is functioning correctly.
  • Check for stable power supply from the vehicle.
