Installation Guide
Follow these steps for a simple and secure installation of your LED strip light:
- Step 1: Prepare the Surface
Ensure the surface where you plan to install the LED strip is clean, dry, and smooth. Wipe the surface thoroughly to remove any dust, dirt, or grease. A clean surface ensures optimal adhesion of the 3M tape.

Image: Step-by-step guide for easy installation, including cleaning the surface, removing adhesive, cutting, and pressing the strip.
- Step 2: Measure and Cut (Optional)
If the 16.4ft length is too long for your application, you can cut the LED strip at designated cutting marks (usually indicated by a copper pad and a scissor icon). Ensure you cut only at these marks to avoid damaging the circuit.
- Step 3: Remove Adhesive Backing
Carefully peel off the protective backing from the 3M adhesive tape on the back of the LED strip. Peel only a small section at a time to prevent the adhesive from collecting dust or sticking prematurely.
- Step 4: Attach the LED Strip
Press the exposed adhesive side of the LED strip firmly onto the prepared surface. Work your way along the desired path, pressing down to ensure good contact. For added security, use the included mounting clips if necessary, especially around corners or areas with potential stress.
- Step 5: Connect Power
Connect the LED strip to the dimmer switch, and then connect the dimmer switch to the 12V power adapter. Finally, plug the power adapter into a standard wall outlet. Ensure all connections are secure.

Troubleshooting
If you encounter issues with your LED Strip Light, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on. | No power, loose connection, faulty adapter. | Check if the power adapter is securely plugged into the outlet. Ensure all connections (strip to dimmer, dimmer to adapter) are firm. Test the outlet with another device. |
| Lights are dim or flickering. | Dimmer setting too low, insufficient power, damaged section. | Adjust the dimmer knob to increase brightness. Ensure the power adapter is providing sufficient power. Inspect the strip for any visible damage. |
| Adhesive is not sticking. | Surface not clean or smooth, old adhesive. | Clean the surface thoroughly before application. Ensure the surface is smooth and non-porous. Use the included mounting clips for extra support. |
| Part of the strip is not lighting up. | Damage to the circuit, improper cutting. | This usually indicates damage to a section of the strip. If the strip was cut, ensure it was cut only at the designated marks. This issue may require replacement of the strip. |
