US Patent 11787253 Transparent light up air tank for holding compressible fluids

A fluid tank for storing a compressible fluid may have a translucent wall is disclosed. A light emitting diode (LED) may be configured to illuminate the wall. The fluid tank may comprise a tube and two end caps. The tube may be coupled to the end caps. Connecting rods disposed in the tube may be coupled to the end caps to squeeze the end caps onto the opposed ends of the tube. The LED may be disposed between one of the end portions of the tube and the end cap attached to that end portion of the tube. When the LED is illuminated, light is projected into the tube so that the tank now has a color to it.
