I will be replacing the wire for the lights. I originally used automotive wire for the lights. However after doing some research I have discovered that while okay to use automotive wire the recommended material is MIL-SPEC shielded or un-shielded wire for use in aircraft. Shielded wire is used for ignition, strobes, and any other "noise producing" electrical connections. Un-shielded is okay for non-strobe lights so that's what I'm going to use for the wing navigation lights. I found nice plain old navigation lights online for a decent price. About $70 per side for normal incandescent lights. These are the lights I ordered.
Regular old incandescent lights for my CX4
I also ordered 100' of 18 gauge un-shielded MIL-SPEC wire to hook them up. I will be taking out the automotive wires shown in the photo above and replacing with the MIL-SPEC stuff then complete the riveting of the skin to the leading edge. Then I'll start attaching the main ribs and getting ready to skin the rest of the wing.
While waiting for my wire I have been fabricating the aileron bell crank parts. I'll put some pics up of that work later.
Thanks for checking in -
Greg.
