These red light bricks interest me. I would like to incorporate these bricks into interactive displays that visitors to our displays can touch. The second reason that I want to experiment with them is to see how useful they are for atmospheric lighting within enclosed spaces. @randomdan seems to support the more powerful 9V lights for this purpose, but after seeing the light brick usage in the Creator Family House set, I want to explore this part in combination with other transparent parts.
This may be an easy selection for the quarterly build challenge, even though my individual build time is booked all the way up through 2019 at this point.
