Review on 🌟 CHINLY 16W Bluetooth RGBW LED Fiber Optic Star Ceiling Headliner Light Kit for Car/Ceiling - Music Mode, APP & Remote Control, Optic Fiber, Adapter, Cigarette Lighter by Eric Alcantara

I drive a 2007 Chevy Malibu so taking the cover apart is easy. On some vehicles this can be more difficult and you may even have to remove the car door. I recommend 450 pieces 9 feet long for cars without a sunroof. The power cable is only 4 meters long. The fibers look like fishing line, the working principle is that light goes through one end and is visible at the other end of the optical fiber, they can be cut to the desired length. I am grateful that the product comes with drill bits and remote control battery. The 450 part is actually from 445, which isn't that far off. It took me 15 hours from start to finish. The lights have many functions, they don't flicker but still look great because there is a music option where the lights change color to the music.
