I will be using the AeroLED Suntail Position/Strobe light. This light requires that the case of the light be grounded. To accomplish this, an uninsulated ring terminal was crimped and soldered to a length of 18 AWG wire. The ring terminal was then place over the tail of the final rivet in the adapter ring and the rivet was pulled, securely fastening a ground wire to the adapter ring.
The remaing wires will be connected to a weather resistant plug to facilitate rudder removal.
