Sure, there are lots of ways of hooking an LED to a voltage source. But
I was thinking about something a little more clean, professional, and
user-friendly.
As my old boss used to say, "We're not trying to win a beauty contest,

Once you solder on wires for extra reach and then some shrink tube to
keep everything from shorting out... I don't know about you, but I have
to start charging for my time.
