No one here is going to (or should) provide you with the circuits.

Figure out how you want to do it. Draw up a schematic and ask questions about the bits you have a problem with.

What's an "electric teaser"?

Sounds like a taser gun to me

555 monostable circuit[/URL] for timing and connect two LEDs, in parallel & back to back, on the output. Terminate the other end of the LEDs to a resistive divider so they light alternately.

Sounds like the OP better clarify this unless he is a masochist.
