Six light rings were attached to six butt stocks with twelve small (#2, M1.5) screws from a hardware store. The hole pattern in the light ring wasn't the same across all the rings since they came from different manufacturers so, in some cases, one of the holes had to be drilled into the plastic butt stock.
Short lengths of light strips were cut with five LEDs on each piece. Angled header pins were soldered to the light strips. Half of the strips were given pins on their output side and the other half were given pins on their input side. At a glance, they appeared identical, so a marker was used to differentiate between the two. It was also possible to read the "DO" or "DI" on the strip to tell the difference.
In order to get the header pins into the mounting holes, the pins had to pierce through a layer of adhesive tape on the backside.
Ten sensor modules, which were already assembled, were given light strips on either side so the sensor could fit between them for power. The adhesive on the back of the light strips was kept in place, even during the soldering phase.
