Review on AZIMOM Fiber Optic Star Ceiling Lighting Kit - Bluetooth/APP Control, 16W, Twinkle Effects, 550pcs 0.03in 13.1ft Fiber Strands, RGBW, Music Sound Control, Light Engine - Ideal for Home, Indoor, Car Interior by Jake Davies

I installed this product on the roof of my car. The process was pretty simple and easy to implement, especially after seeing others doing it on YouTube. The fiber optics were all long enough (I bought the 9ft version) that they reached anywhere in the headliner I wanted to be the star. The signal from the remote reaches the trunk where I installed an alternator which is great. The only thing I had to buy was a 10 foot DC power cord because the included 6.5 foot DC power cord was too short, but I remounted mine in the far corner of the trunk. Customer service was great because they gave me accurate information on which 10ft DC power cord to buy and was very quick to respond. At night, the results from this outstanding headliner are AMAZING! I can't believe this is in my car! Easy to turn on and off, remote control with options is cool. My overall impression is that this is a great product and will give fantastic results when installed correctly!
