6 Channel Auto Reverse Sequential Running Lights

[audioguru2]

On the schematic, R3 should connect to the LED anodes, but not to T1 as shown.

Thanks for showing me the error. I must have by mistake done it the
other way.Good obsevation.Can it be changed in anyway?

Are you going to build it?Please tell me how it works.

On your schematic, I can't see where the diodes connect to.
I built a similar Knightrider circuit that uses only LEDs and it clearly shows the diodes:

Please compare its diodes to yours. Thanks

i have darkened the points in the schematic diagram where the diodes connect.I have made this schematic diagram on PAINTBRUSH.

Your 4017 pin numbers do not seem to be in the proper order for the lights to be sequential. For example, 4017 pin3 should feed the 1st light, but you have pin1, pin 4 should feed the 3rd light, but you have pin 2 etc. Don't you have them mixed-up? And the diodes?
You don't talk about the switch but I think that it is used to shorten the sequence, but position 4 seems to light only one light continuously instead of 5 lights. All other switch positions seem OK. Please check your switch position 4.
What is the regulator used for? With your well-filtered 12V unregulated, the parts don't need it.

Okay.
I fix the circuit again and go through it again.
Thanks for pointing out the mistakes.
You are good.

Congratulations for your win in the contest!
And thanks for listening.

It was the first time i designed a circuit on my thoughts and half of the circuit matched with yours.Good experiance for me.
THANKS!!!!!!!!!!!!!!!!!!
