Abstract: A sign assembly may include a display portion and an arm extending from the display portion. The arm may be moveable from an at-rest position, through a warning stroke in a first direction upon engagement with a vehicle to a fully extended position at an end of the warning stroke. An arm retraction mechanism may cooperate with the arm so as to provide a resistance force toward the at-rest position upon vehicle engagement while the arm is moving through the warning stroke. The retraction mechanism may be further adapted to return the arm to the at-rest position upon disengagement with the vehicle.

Abstract: An illuminated sign and method of making includes a series of characters formed of solid, substantially transparent material. The series of characters may collectively define a footprint and a first thickness. A sheet of material, formed separately from the series of characters, defines a base and a second thickness. The base defines a series of openings formed therein and collectively defines a shape suitable to accept the footprint defined by the letters in an assembled position. A housing retains the base and has a light source therein. The light source may be adapted to direct light through the base and the series of characters.
