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.

An inline clip for holding a light bulb along a light string includes a top flat area, two symmetrical sides, and two symmetrical tabs. The flat area has a constant width extending across a side profile and a constant thickness extending from a top surface of the top flat area to an internal surface of the top flat area. The two symmetrical sides extend in a continuous manner at respective upper ends from a left end and a right end of the top flat area, and are arcuate shaped for forming a hollow interior space configured to receive within the light bulb and a portion of the light string aligned side-by-side along a diameter of the light bulb. The two symmetrical tabs extend in a continuous manner at respective connecting ends from the lower ends of the two symmetrical sides.

A lighting assembly is provided that includes a light fixture in combination with a support grid such as a drop ceiling t-bar. The light fixture can be configured to use a t-bar as the main form of support. The light fixture can be push-fit onto a t-bar or use a clip to join two or more portions of the light fixture to an installed t-bar. Once attached to the T-bar, the light fixture itself can provides support for a ceiling tile. Various embodiments are provided which achieve a variety of light distributions useful in typical illumination applications. Both recessed and suspended fixture types are achieved in various embodiments which are particularly well suited for LED lighting.
