Customized light indicator for wall switches.
Holes were made with a piece of tungsten carbide drill with engraving tool. After milling holes were filled with clear glue. LEDs are covered with pieces of opal diffusor and a piece of white thick paper (120 g/m2) for additional light scattering.
Switches control low-voltage signal, no mains voltage is applied. LED's are driven independently by light control unit.
