This is an RV-4, an Experimental amateur-built aircraft.

I started building this aircraft on Friday, April 13, 1990, and the first flight was May 26, 2008.

RV4 going really fast.  Note the speed on the upper left corner of the Garmin 496 GPS.  A nice tailwind that day (69 mph).

The wing tip strobes are Whelen units for law enforcement & emergency vehicles.  Much cheaper than aircraft units, but are very similar in appearance and power specs.  $190 for power supply, cables, and 4 strobes. 

The wing tip nav lights are automotive LED light bulbs with 1156 type socket.  Simple & cheap.  Compared to standard light bulbs LED's use much less current, run cooler, tolerate vibration better, and last longer.  45636 ($12) is what I used but it looks like there are other good options now such as 47615.
Sockets... NAPA LS6219, $6.49. This unit mounts flush and has two screw type terminals.

The tail light is a Whelen A500-14 nav/strobe combo.
