Good Point Kirk, here's a pic of the lights included...
I put a set of metal wingtips on my plane. Quite nice, and very sturdy. The only caveat is for those people switching from stock Cessna plastic wingtips - the nav lights are different. Stock Cessna uses truncated wing-tip nav lights, whereas the metal tips use the standard Grimes teardrop-shaped lights.
In my case, I was looking for that - I wanted wingtip strobes and the metal tips meant the Whelen nav/strobe combo would bolt right up.
