I cleaned these up a bit more. Way back in the day, I acquired a set of RV9 FlyLED wingtip boards. They were reshaped to make them fit the RV7 wingtip coves, but the ribbon 4 conductor wire that comes with them was too short, so I made up connections with individual wires, secured against vibration with zip ties to a base glued down with E6000.

I also used a bit of E6000 on the VOR antenna to keep it from vibrating and cutting into the inside of the wingtip.
