A water and lighting display that includes an unmanned aerial system (UAS) is disclosed. The UASs may illuminate water shot out of the water fountains, may fly in formation or may include removable payloads.

An emergency sign with orientable light assemblies is an apparatus that displays a message or instructions and alerts nearby individuals of an emergency or event. The apparatus includes a sign, a first orientable light assembly, and a second orientable light assembly. The first orientable light assembly and the second orientable light assembly each include a brace, a post, a sleeve, a carriage, a track, and a light fixture. The first orientable light assembly and the second orientable light are mounted onto the sign and are opposite each other about the sign. The brace positions the light fixture about the sign. The sleeve integrated into the brace and the post is rotatably connected within the sleeve so that the light fixture may spin. The carriage is terminally mounted to the post and the track is integrated into the light fixture so that the light fixture may laterally slide.

Disclosed is a wheel dynamic imaging display rack which comprises a frame. A sleeve is fixed to the frame. A hollow shaft motor is fixed to the sleeve. The hollow shaft of the hollow shaft motor is fixedly connected to the wheel through the sleeve, the hollow shaft motor can drive the flange, the wheel and the LED lamp blade to rotate, and clear images are shown in the LED lamp blade.
