There should be no need to change the current limit resistor. With the stock resistor, a modern blue LED will be many times brighter than the green one it replaced. If anything, I wish mine had a little larger resistor so it wasn't quite so bright.

I think the problem Jason is having stems from the fact that his LED is infrared, not blue. It's just simply NOT going to put out any visible light unless you REALLY put a lot of current through it... then it will put out both light AND smoke... (-:
