Installed left wing light. Knowing what you are doing makes for real quick work. the right light took me nearly 2 hours to put in . This one just under 1/2 hour. And to make the iceing on the cake even sweeter we got the correct lights on the correct wings YAAAAA!!! ( we hooked them up to the Battery to test). The walls on these wing tips are very fragile. Care must be taken not to push to hard on the drill bit or you could crack the fiber glass. We also used heat shrink tubing to cover all the connectors inside the wing tip. The connectors are stagered so as to permit for threading of the wire through the wing tip hole seen in fig. 1
