[HomeBrew] Two color LEDs

[Dick Foster]

Does anyone have a simple circuit for driving dual color (red/green) =
LED's?  That is, the two leaded kind which are red polarized one way =
(e.g. +/-) and green the other (-/+).  No relays please.  I'm looking =
for solid state solution.

Op amp's can reverse output polarity, but they're usually pretty low =
current.  Need about 10 to 20 mA for most LEDs.

Very 73,
