Pilot light

I am trying to do wire a program using a single timer to turn on a pilot light 1 through 8 in a sequence to 1 sec intervals. When all eight lights are on the are turned off from 8 to 1 in sequence at 1 sec intervals. I have to use one timer and the rest are compare instructions. does any one know how to do it is logixPro outputs are 0-7 and on off is I:1/0.

I feel like I am doing your homework problem for you but attached is a rough example that will do 4 lamps. You can expand it out to 8.

8 light Sequencer

Attached is a printout of the program using LogixPro.

I put the original program written in LogixPro in the downloads section. Here is a link:
