Hey thats a good idea! A little black modeling paint from a hobby
shop, what was it...Testers? Wow hadn't thought of that since I was a kid.
Maybe alittle black nail polish if there is a female you know who could lend you some.
I had recently removed the tip of my 510 to look inside for the heck of it. All I saw wa a little tiny tiny led mounted on a small board.
Had two wires attached to power it.
I would imagine you could just clip the wires and terminate insulate the ends so they don't short out.
I just used my fingernail to pry off the plastic tip on the end of the batt.
If I were to try removing the led, I would clip the wire so that you do not see any exposed metal.
Then to insulate the ends you can use all kinds of things. Heck a tiny bit of scotch tape would be sufficient. You could dab a tad of Elmer's glue or even super glue to seal it then add the scotch tape.
Scotch tape would be sufficient because of such a low voltage going thru the wires.
I'm curious to know how it would work out. Please post if you try it and how it works out.
