Inspired by Thingiverse's https://www.thingiverse.com/thing:2120195, this design incorporates a fixing bracket that serves as a holder. This is an upgraded version of a light bar system. The LEDs are powered by +12V and divided into two groups, with the 3-LED group using 10 ohm resistors and the 2-LED group utilizing 33 ohm resistors for optimal brightness control.
