I have built a low frequency oscillator using lm324.
the setup is being powered by a dual supply of +5v and -5v , having a ground.
i would like to drive 2 leds , one for the positive part of the cycle and one for the negative part of the cycle without loading the signal. i know i could just connect the output signal to two inverted LEDS in parallel connected to ground but i do not want to load the signal.
can any one of you guys tell me how i can use generic transistors to do such a thing ?

the positive signal led was not so hard to do using 3904, its the negative part that's making me crazy.
