Lego compatible 1x3 traffic light

I'm deep into automating Lego trains (Digispark Arduino compatible cards on board of trains, radio-wave controlled, ...). I couldn't find a nice way to build a traffic light with regular bricks that wasn't too massive. I thus decided to 3D print my own.
A 1x3 brick compatible brick, with enough room to hide soldering and resistor. 4 different covers : 2 for 3mm LEDs, and 2 for 5mm. For each size, a vertical and an horizontal cover.
