wire gauge for grain of rice led

[eneg]

need a little help here , what gauge wire to use for grain of rice led?

[jrbernier]

  They usually draw less than 20 ma - as small as you want as long as the distance is not across the room!  I use #22 wire for lighting feeders.  For Locomotives I use #28-30 flexible wire as we are talking 'inches'...

 You can run these things off stuff like #36 enameled magnet wire - it's what many commercial signals use for their internal wiring. You can solder the LED's leads to piece of #10 solid too, if you like. Basically, since the current draw is so low, you can use whatever size of wire fits best where you need to run it, no worries on the size. Too big won't physically fit, and the smaller you go the harder it is to work with. You don;t even need wire - if you are making say a brakeman holding a lantern, you cna use conductive paint instead of wires so there's nothign to hide - paint the conductive traces then paint the 'uniform' on the figure to hide and protect the conductive traces.
