I found them on Amazon. You can get 2-12 lights depending how many you need. I plan on placing one under dash for each the driver and passenger sides and 1 above each wheel well inside in the back. You can choose between any color you want and dim the brightness too. All controlled with your smart phone. Turns on with your phone too so no need to install a new Rocker switch to turn them on and off. My EB is so dark inside I needed some interior lights.
Each light uses between 6-9 watts depending what you get. So with 4 lights on the circuit I figured I'd run the main power wire to my new fuse Box and install a 5 Apms fuse.
Fuse required = total watts on circuit/Volts X 1.25
9watts X 4 lights/ 12 volts X 1.25= 3.75 amps fuse
