Show me your Light-Mods

Hello SoliForum'ers

Show me your lighthacks for Da Vinci :-) I am currently doing a small control-panel for lights and maybe octoprint, and would love to see what else you have made out there.

Especially, im interested in knowing if you've build anything into the rails of the DaVinci Jr (and pro?) or you just taped it on.

Pics or it didn't happen
