Disco lights DIY with Arduino

Depends what you want. I’d go with a microcontroller for starts so you can change it programmatically. I’d bet someone has done it with an Arduino or Pi. Here are some links to interesting looking projects. Those circuits operate mostly at safe low voltages and control low power LEDs. The same ideas can be used to control higher power lights with help of FETs or SSRS (if you know how to do that safely).

Disco LED
It is a simple tutorial on how to create disco lights.

Build disco lights that flash to the beat of the music. The sound sensor in the Maker Kit can track music, and at the same time, we’ll learn how to flash five leds independently with Arduino.

PROJECT 4: DISCO STROBE LIGHT

Turning the potentiometer up or down changes the speed of the flashing lights, creating a strobe effect. You can use red and blue LEDs for a flashing police light effect.
