how do i connect LEDs to my (electric) guitar that light up as i strum?

i have had this idea in my head, about making a custom guitar that lights up as i'm playing.
i've came up with several ideas, like sound to light... but it picks up background noise.
an idea i had, was to do a direct attachment to the pick-ups... but i don't want it to mess with the sound (distort or make it weaker).
i've searched and searched and i came across the idea of using some kind of switch that turns on when it feels a current.
i think they said something about transistors or something...
i don't know... i just need help.

You can make a very sensitive switch in every place the strings are connected to the board. As you will play your guitar, the strings should touch the switch thus, turning the switches on and then off.

I think that direct attachment to a pickup might work well. You just need

to add a dedicated pickup that is used only to drive the transistor circuits that

turn the LEDs on and off.

Use sound reactive LED's:

Look up how to make a clap circuit. In place of the microphone for the circuit wire it to the 1/4" jack on the guitar. You'll need to have a battery on the circuit to make it work.
