LED taillights are truly great.  Shortly after GM started putting them
in the back of some Cadillacs, some hobbyists came out with a retrofit
kit to install similar lights in my truck; I bought one of the first
kits, since I was sick of the bulbs which were dim at best and
probably downright dangerous.  Considering that the taillights are
perfectly rectangular (1970 GMC) it probably didn't take a whole lot
of work to plot out a rectangular PCB with 168 LEDs and three wires to
a standard 1157 bulb socket.  The result is amazing.
