These mounts eliminate the need to drill mounting holes in fenders or fender struts. They come complete with neoprene bushings to ensure a good fit to any 1" (25mm), 1 1/8" (28mm) and 1 1/4" (32mm) tube, such as used in most Softail swing arms. Originally designed by Adjure for their Beacon-1 and Beacon-2 turn signals but, as they are 5/16"-24 UNF threaded they will also take stock or aftermarket Deuce-style turn signals. Wires exit the bracket from the bottom enabling an extremely clean installation. Precision made from forged aluminum, then hand polished and perfectly chromed. Sold in pairs.
