I've been searching everywhere online and haven't found anything that would help me make a device that would take in my 3.5mm input and output LEDs that synchronize to the song I play. I don't want a meter or any bars. I have two light bars already that are rated for 12v and I can hook them up to whatever. I just want something that will work in my car (run on 12v), take in a 3.5mm input, and have 2 wires that i can use for the positive and negative on my light bars, which are LED. Any schematics or input would be greatly appreciated. Thank you in advance.
