Embodiments are generally directed to a sound-dampening light fixture. In one embodiment, the sound-dampening light fixture includes the following: a structural center portion that includes a housing for a light source, and at least one interconnecting ring that includes connection points for connecting panels to the interconnecting ring. The sound-dampening light fixture also includes panels arranged circumferentially around the structural center portion. The panels are connected to the interconnecting ring at the connection points. The panels are arranged at angles that are designed to dampen sound waves, and are constructed from material that further dampens sound waves coming into contact therewith.

Methods and apparatuses are provided for improved traffic control devices including a continuous central hanger support system that is integral to the traffic control device and provides a central load path. In an embodiment of the invention, the terminal housing and traffic signal housing of the traffic control device can be included in a single unit housing. A single unit housing can also include an integral backplate. Also provided are span wire clamps, tether clamps, and mast arm clamps that can be used to affix the continuous central hanger of the traffic control device to various fixtures such as a single span wire, two span wires, a pole or a mast arm. The continuous central hanger integrated with the single unit housing can provide the traffic control device with improved securement of electrical components and structural stability for survivability during high wind events as compared to conventional traffic signal devices.
