Years back I had started converting my 9v train engines for lights. The idea was
to light up some of the cars on a train. I used LEGO wire jumpers that I cut to
tap off the motor, but you can always use off the shelf battery holders and wire
it yourself. For connectors I used female .1" spaced PC connectors, similar to
those used to connect the switch and LEDs to the mother board of a computer. You
can use the PC board mounted part (male) as the other half of the connection, or
a jumper between two of the female connectors. The nice part is that these are
small, some even fit through a hole in a technic brick. They are also the
correct size to slip onto the shortend leads of an LED.
