$200 DIY STARLIGHT HEADLINER ✨ Most shops charge $1500–$3000 for this upgrade, so I decided to show how to do it yourself step-by-step. From removing the old headliner, painting it black, installing the fiber optics, wiring everything up, and putting it back in the car — the full process is now on my YouTube. Watch the full video on my YouTube 🔥 Link in bio. Would you install this in your car? 👀 #starlightheadliner #carinterior #diycar #carcustomization #fiberoptics interiorupgrade
