This DIY is performed on a 9th gen Corolla but you can do this on any car .
All you need is a 36 LED panel and a small pick/hook tool .
As you can see with the second photo gently remove the cover for the dome light by hooking the one end of it . As you will see the bulb . Make sure the bulb is off cause it can be hot and burn you if left on .
The LED panel comes with a kit so find the kit that properly fits your needs . Make sure color of the wires are plug in correctly .
Once you have it working then put the dome plastic cover back on and there you have a easy DIY and a bright interior of a car .
