Summary

I picked up these super cheap LED hat lights are a popular superstore (Which I also work at) so I could hack them into layer lights for my printer. Since the HE-280 upgrade, my old chassis-mounted lights no longer work due to the proximity to the wider fans, so having an effector-mounted light was a much better solution.

Couple spots of super glue on the PCB where the two angled tabs line up, then wire it to the "Optional light" tabs under the black cover.

Included a stock image showing the hat lights I hacked. Others may work better, but these work pretty well.
