led notification help

[tritan]

I have downloaded a bunch of apps like any Newbie for my droid x including K-9 and maildroid. I have mail droid and the default email off I believe and using K-9 for testing . I keep getting the led flashing pink/purple and can't figure out how to change it . I had pop sms at one time but deleted it for handcent sms. Is there settings any where for on the droid x itself for changing the led for missed calls etc?
