Please zip the file you uploaded to mediafire.com, then attach it here using the Go Advanced button. This site won't allow a .rar file but will allow a .zip file. It it better to have the file on this website than on an off-site location.

Edit:
I will do this for you.

Here attached are the files in .pdf form and in .zip form.

Must you use 3 timers? I can see how to do it with 2 timers, but I don't know what you will do with the 3rd timer! Here (attached picture) is a program that works with 2 timers and 1 counter. The same 2 timers control all 3 of the lights. You can set the timers for whatever ON time and OFF time that you need. The Preset value of Counter C5:0 must be 7, not 5 as you had it. Use the comparison instructions LEQ (Less Than or Equal) and EQU (Equal) to control when each light goes ON.

Challenge: Can you do it with 1 counter and NO timers at all? There is a way using "S:4/9" internal clock bits.
