4. Installation
The K2178 Security Solar Light is designed for easy, self-contained wall mounting. Follow these steps for optimal performance:
- Choose a Location: Select a location that receives direct sunlight for 6-8 hours daily to ensure the solar panel charges effectively. The recommended mounting height is 3-10 inches for optimal motion detection.
- Mark Drill Holes: Hold the mounting bracket against the wall at your desired location and mark the positions for the three screw holes.
- Drill Holes: Use a drill to create three holes at the marked positions.
- Insert Expansion Plugs: Insert the provided expansion plugs into the drilled holes.
- Mount the Light: Align the mounting bracket with the expansion plugs and secure the light using the provided screws. Tighten firmly.
- Adjust Angle: The lamp head features a 360° rotating bracket, allowing you to adjust the lighting and detection angle as needed.

5. Operation
The K2178 solar light operates automatically from dusk to dawn and can be controlled via the integrated ON/OFF switch or the included remote control.
5.1 Initial Setup
Before first use, ensure the product switch is turned ON. Allow the solar light to charge under direct sunlight for at least 8 hours to activate the battery. Remove the insulating paper from the remote control's battery compartment before use.

5.2 Lighting Modes
The light features three distinct operating modes, selectable via the remote control:
- Mode 1 (Sensor Mode): When motion is detected, the light turns on at full brightness. After approximately 15 seconds of no motion, the light turns OFF. Red warning lights may flash.
- Mode 2 (Slight Light Mode): The light stays dim to conserve power. When motion is detected, it becomes fully bright as a warning. After approximately 15 seconds of no motion, it returns to dim light. Red warning lights may flash.
- Mode 3 (Dim Light Mode): The light maintains a continuous dim illumination throughout the night.

5.3 Remote Control Functions
The remote control allows you to switch between modes and turn the light ON/OFF:
- ON: Turns the light on.
- OFF: Turns the light off.
- MODE 1: Activates Sensor Mode.
- MODE 2: Activates Slight Light Mode.
- MODE 3: Activates Dim Light Mode.
- SOS: Activates an emergency lighting situation (automatically lit).

6. Solar Charging
The K2178 light is powered by a built-in lithium battery that charges via its integrated polycrystalline silicon solar panel. It charges during the day and automatically illuminates at night, providing zero electricity cost.
- Daytime Charging: The solar panel requires 6-8 hours of direct sunlight to fully charge the battery.
- Nighttime Operation: A fully charged battery can provide 8-10 hours of illumination.

7. Maintenance
To ensure the longevity and optimal performance of your solar light:
- Clean Solar Panel: Regularly wipe the solar panel with a soft, damp cloth to remove dust, dirt, or debris that may obstruct sunlight absorption.
- Clear Obstructions: Ensure no trees, buildings, or other objects block direct sunlight from reaching the solar panel.
- Battery Care: The built-in lithium battery is designed for durability. Avoid prolonged storage in a completely discharged state.
- Weather Resistance: The IP66 waterproof rating ensures the light is protected against rain, snow, heat, and frost. However, extreme weather conditions may temporarily affect performance.

8. Troubleshooting
- Light does not turn on at night:
- Ensure the main switch is ON.
- Verify the solar panel is receiving sufficient direct sunlight (6-8 hours) during the day.
- Check if the remote control's insulating paper has been removed.
- Light is dim or short-lived:
- The battery may not be fully charged. Ensure the solar panel is clean and exposed to direct sunlight.
- Consider the weather conditions; cloudy days reduce charging efficiency.
- Motion sensor not working:
- Ensure the light is in Mode 1 or Mode 2.
- Check for obstructions blocking the sensor's field of view.
- Verify the sensor distance (4-10 meters) and angle (120°) are appropriate for your setup.
- Remote control not responding:
- Remove and reinsert the insulating paper from the remote control.
- Ensure the light's main switch is ON.
9. User Tips
- For best security, mount the light in a prominent location where the fake CCTV design is clearly visible.
- Experiment with the three lighting modes to find the best balance between security and energy saving for your specific needs.
- Regularly check the solar panel for any accumulation of snow or leaves, especially during winter or autumn, to maintain charging efficiency.
- The 360° rotating bracket is very useful; adjust it to cover the most critical areas for motion detection and illumination.
