How do i make a 555 IC timer chip make two leds flash back and forth like a light bar? Answered

What i am trying to do is make my leds flash at different times. i have a 555 IC timer chip and have found how to make a single light flash using resistors and capacitors. How would i go about making two leds flash back and forth. Any information in regards to this would be greatly appreciated.

Well, according to this circuit by connecting LED1 between pin3 and + and LED2 between pin3 and -. I've done this at some point to make a push-pull curcuit.

The simplest way to do this is to hook up two transistors to the output of the 555 timer. One must be NPN, and the other must be PNP. This will provide two alternating outputs that you can hook LED - resistor combinations up to.
