  • Using 4.3 inch LCD as brake light

    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.
