Abstract: A lighting pole bracket arm isolates vibrations that would otherwise pass through the lighting pole and into a lighting fixture mounted on the lighting pole. The bracket arm includes an upper member which is pivotally mounted to the lighting pole and a lower telescopic member, which is pivotally mounted to the lighting pole at a position below the upper member pivotal mount. The lower telescopic member includes an inner tube that is slidably received within an outer tube. A cylindrical oil-free sleeve bearing is press fit over the end of the inner tube that is received within the outer tube, and a second cylindrical oil-free sleeve bearing is press fit into the end of the outer tube that fits over the inner tube. A coil spring is housed within the outer tube between a closed end of the outer tube opposite from the end having the sleeve bearing and the end of the inner tube slidably received within the outer tube.
