Primed the trailing edge skin where the tail light bracket attaches with zinc phosphate primer. Used butt splices p/n 320559 (Aircraft Spruce) to connect the tail light to 18 awg. wire. Also used heat shrink p/n HST-1/8 and HST-3/16 (Wicks) to hold the wires together. Riveted the tail light bracket to the rudder with 10 ea. A4 rivets. Screwed the tail light to the bracket with #6 screws and tested the light to make sure it works.
