A traffic marker illumination device for improving the visibility of a traffic marker to provide warnings for constructions sites and roadways. The traffic marker illumination device is designed to removably attach to an interior portion of a traffic marker. The traffic marker illumination device generates a light to illuminate the traffic marker based on the geographic position of the traffic marker and surrounding environmental elements.

A safety trailer is shown including first and second platforms, at least one of said first and second platforms having an axle and wheels attached thereto; a plurality of interconnected wall sections positioned between and connected to the first and second platforms, the plurality of wall sections defining a protected work area on a side of the trailer; and wherein the trailer supports a ballast member, the ballast member being positioned near a first side of the trailer and the wall sections near a second, opposing side of the trailer, the ballast member offsetting, at least partially, a weight of the plurality of wall sections.
