Review on 🌈 10W RGBW Fiber Optic Sensory Lights for Autism Sensory Room with Twinkle, Music Response, Bluetooth App Control - AKEPO Fiber Optic Light Engine (3x0.75mm) Flash Point Cable, 50pcs of 6.5ft/2m in Length by Douglas Irwin

I didn't understand you needed a light source, it isn't supplied and when I wanted to check what source I needed I looked at the video and each one just shows the music and the lights moving towards it then i tried to contact the company as they say but of course no answer so i have this thinner optical rope which is pointless until i figure out what source i need and I'm sure it will be expensive should they post that it's a replacement rather than thinking it's all together so it was my granddaughter's Christmas present
