Hello all,

First of all I am not sure where to post this as I couldnt find any similar threads because I dont know what to search for.

Let me try to explain my silly idea.

I want to install two 4.3 inch LCD screens on my rear bumper where the reflectors are curently on. This car is going to be a show car.

And I want the display to light up Red when I press my brake
Turn fully white when i reverse
Display Audio spectrum or grahics when playing music
Display rolling messages
Display music video etc...

I have seen this been done on the Demo BMW for Alpine.

Is this been done by anyone here? I am not looking at exactly same thing. Hoping to see if someone used vehicle 12v input as signal interrupts.

Can someone guide me to a starting point or thread?

Really appreciate the support.

Thank you.
