What happens in this clip
After successfully running all 15 cables through the skirt board, the next step is to install the LED strips themselves. The LED strips come with a 3M adhesive backing for easy installation. First, measure and cut each 40-inch LED strip to fit the length of your specific stair treads (the video states the stairs are 37 inches long). Make sure to cut the LED strips at designated points indicated in the kit's instructions to maintain proper functionality. Once cut, simply peel off the adhesive backing and firmly attach the LED strip to the underside of each stair tread, ensuring it is straight and secure.
Goal: Attach LED strips to each stair tread.

About the full video
This project guides you through installing motion-activated LED lighting on hardwood stairs. It covers planning, drilling holes in the skirt board, running cables, installing LED strips, connecting to a controller, and finishing with corner trim. The system uses a KOMIGAN intelligent motion sensor LED stair lighting kit, providing both aesthetic enhancement and practical illumination for stairs.
Step 2 of 7: Cut LED Strips to Length
Based on your layout plan, measure and cut the LED strips to the appropriate length for each stair tread. Most LED strips have designated cut marks; ensure you cut only at these points to avoid damaging the circuitry. You will likely need to cut multiple strips, one for each stair.

Questions about Staircase Lighting
What are the most crucial safety precautions I need to take when installing electrical components for this project?
Always turn off the power at the circuit breaker that controls the staircase's lighting circuit before starting any wiring. Double-check that the power is off using a voltage tester. If you're unsure about any electrical work, consult a licensed electrician to ensure compliance with local codes.
Is a soldering iron truly necessary, or can I use an easier method to connect the LED strips?
While soldering provides the most robust and reliable electrical connection for LED strips, many beginner-friendly kits offer solderless connectors. These 'quick connectors' simply clip onto the strip ends, making the process much faster and easier if you're not comfortable with soldering.
What type of LED strips and motion sensors should I choose for the best results on a staircase?
Opt for 12V LED strips with a consistent light output (e.g., 60 LEDs/meter) and a warm color temperature (2700K-3000K) for a cozy ambiance. For motion sensors, choose PIR (Passive Infrared) sensors with adjustable sensitivity and time delay, ensuring they cover the top and bottom of your staircase effectively.
What is a common mistake beginners make with motion-activated lighting, and how can I avoid it?
A frequent mistake is improper motion sensor placement or sensitivity settings. To avoid this, temporarily position and test your sensors before final mounting. Experiment with their angles and sensitivity to ensure they reliably detect movement on the stairs without false triggers or dead spots.
Is the 8-hour estimated time realistic for someone new to DIY electrical projects?
Eight hours is a reasonable estimate for a beginner, assuming you have all materials and tools ready. Planning the layout, carefully cutting and connecting strips, and concealing wiring can take significant time. Working methodically and allowing for troubleshooting will help you stay within or close to this timeframe.
What are the best methods for concealing all the wiring and making the installation look professional?
To achieve a clean look, route wires along discreet edges, such as under stair nosings or behind the kick plate. Use small adhesive cable clips or wire channels that match your staircase color. Planning your power supply and sensor locations carefully from the start will minimize visible wires.
Are there any alternative power supply options if I don't want to hardwire the system?
For permanent motion-activated staircase lighting, a dedicated wired 12V power supply (transformer) is recommended for consistent performance and safety. While some temporary LED solutions use batteries or USB, these are generally not suitable for a robust, always-ready staircase illumination system.
