Does this have to do with my LED flash light topic?

A 555 and an octal counter chip. Tie output lines 0 and 1 to LED #1, lines 2 and 3 to LED #2 and line 4 to the reset line. Lines 5, 6 and 7 would be unused.

I would suggest using a 556 timer AND a 555 timer. A 556 timer is basically two 555 timers, only in one cheaper, more convenient package. You can use the 556 for LED#1 and a delay for the power to the other 555 timer.
