Can an led brake light pulled from a spoiler be used inside my car and beat to the bass in my music? Answered

So i pulled out an led brake light from an old nissan spoiler that has its own circuit and resistors on the board with only + and - wires coming out. Is there any way that i could hook it up to the headphone output that i have in my current car? I know that i have to use a tip31 transistor but i dont know how to wire it up.

A photo of the board would help here. Attempt connecting the + and - wires to a speaker output anywhere ( inside the house, or car ) I have come across some LED circuits similar that have made a 'visualizer' effect and played to the tunes of the music using this method. Turn the volume up and see if you can see a signal getting to the LED's, but not too high if it is a decent amplifier. ( I remember using an LED display from a massive cardboard book that had board games like snakes n ladders. LED's were in the electronic die ( dice ) )

You may have to hack the circuit / LED's so they will work with a completly new one like you have asked, using some basic components and IC's like a LED driver ( LM3914 for example, many tutorials online to make what you want with these )

Because it is a tail light as well - I wouldn't be expecting all the LED's to function as of weather / rain, and knock damage from being in the car previously.

All the leds in the circuit work, I tested them with a ac to dc transformer here in my house. I'll take a picture later today though. I'm gonna have to wait til tomorrow so I can try to plug them in my amp. It works on 12v DC because it came from a car.

I would check for VU METER and go from there.
