ABSTRACT:
A light on a self-supporting collapsible arm having a plurality of frictionally restrained articulating joints, where the frictional joint has a male half joint with a first plate and an annular shaft with an inner wider diameter. In the surface of the first plate is a first O-ring seated in a first groove. A matching female half joint has a second plate and coaxial to the bearing in the surface of the second plate is a second O-ring seated in a second groove. The opposing side of the second plate of the female half joint has a third O-ring in a third groove. The third O-ring tensions a snap pin that couples the male and female half joints. The snap pin has a head with a compressible ridge which expands when the snap pin is pushed in far enough to engage the inner wider diameter of shaft.
