Abstract: An optical traffic signal column including stacked levels fixed to one another by rotation. The base of each level includes, distributed along its periphery, oblong passages and fixed connectors. The conductors include rods each having two ends angularly offset from one another, and including a common conducting rod and a stage-specific conducting rod. The connector rods are identical and respectively fix the bottom of a conducting rod of the relevant level and the top of the respective conducting rod of an adjacent level, the angular offset between the two fixing points corresponding to that of ends of the conducting rods. The conducting rods are mutually arranged and mounted to effect, from one level to the next level, an essentially identical angular position of the common conducting rods and an angular offset of the stage-specific conducting rods.

Abstract: A sign assembly can be formed by attaching several modules together. Each module includes a lamp assembly for back lighting the sign display, and has walls with a plurality of dovetail grooves in their exterior surfaces. Double dovetail unions engage the dovetail grooves in abutting walls of a pair of modules to fasten those modules together.
