I've used Sandmann's instructions to make LED inserts for both my Americas...
Really easy to do, and if you're a little bit too clever can make it the easy way to put two LEDs in the indicator. And before anyone argues.....yes you can as I have done it. Make it the same as the other ones, but put two really stupidly bright LED's in....just use 3mm ones and put them in parallel, just reverse the polarity of one of them.
