A worm clamp marker holder is provided. The worm clamp is connectable to a buryable element such as a pipe. A marker may be removably attached to the worm clamp by way of a holder connected to the worm clamp, to extend away from the buryable element allowing it to be easily identified once buried.

A marker cone system which provides users with greater spatial awareness and guidance when using marker cones for sports training or other sports and/or non-sports related activities. The marker cone system generally includes a weight which may be installed underneath the marker cone and a post receiver which may be installed within the channel of a marker cone. The post receiver and weight will generally be connected together, such as by threaded engagement, with the marker cone being secured therebetween. A marker post may be removably inserted within the post receiver to improve visibility or provide additional functionality. The marker post may include a slot to reduce wind resistance and one or more receiver openings adapted to removably receive cross members. By utilizing multiple marker posts with post receivers, one may construct a hurdle, fence, goal, or any number of structures for sports or non-sports applications.

A flashing beacon may include a signal unit, a control unit associated with the signal unit, a solar panel or collector, and an activation device that may all be mounted or otherwise positioned on a post of a roadway sign. Light units associated with the signal unit may be programmed to flash on and off in a unique wig-wag pattern. Further, a light bar may also be used with the beacon to generate an intense flash of light soon after activation of the beacon as an additional means of grabbing the attention of the operator of a vehicle.

A safety or sports cone with controlled illumination is provided that is durable and easy to use. The cone has a light-transmitting body with an illumination device housing integrated into the top of the body that houses an illumination device that rests on a support ring and is accessed by a housing cap. The illumination device includes a light-emitting diode (LED) module, an LED actuator, a battery, and a battery housing. The illumination device is covered by a protective transparent shell. A reflective platform increases the illumination intensity at the top of the cone and provides additional protection from physical damage and contaminants. The illumination is activated and deactivated by pressing the center of the housing cap to affect the LED actuator. One or more ridges extending from the inner surface of the body below the support ring prevent unwanted activation of the illumination device during cone stacking.

A dynamic message sign includes a front housing defining a viewing window and an interior. A LED assembly is in the interior for displaying a message within a cone of vision. A louver assembly limits the cone of vision. The dynamic message sign may also include a back frame for supporting the front housing and a bracket for setting the front assembly at an angle with respect to the back frame. The LED assembly can include a plurality of LED pixels arranged in rows and columns. The louver assembly can include a plurality of louver racks, each louver rack extending adjacent to a column of LED pixels.
