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.
