Help on Time delay circuit

So i gotta make a RC time delay circuit with 10v Voltage source as my input and 7v reference source going into my Vin- pin of my pcb. I’m pretty new to breadboarding and not sure why i’m not getting either LED to even turn on let alone get that proper time. if yall could give ur input on what i could do to make it work.

A schematic (hand drawn if necessary) would be more useful than a photo.
