12v timed relay needed

I have 2002 Vw Jetta and what I’m trying to do is put a timed relay to turn off my driving lights after about 30 sec. ignition was turned of and the switch remained on. Like stock  2003 Acura TL has.   So I’m means it has to pass current when the ignition is turned on or cycled and remain turned on for 30 sec?  Any help would be appreciated. Thanks Guys! 

What you are looking for is an off delay.

When in doubt, try it out !

hotwaterwizard  Thank you !!!!!!

Please let me know how it works, I designed it myselfJohn DeRosa (Hotwaterwizard)

Not sure yet what is the difference between NPN and PNP? what does that stand for?

Hotwater, Did you try it with the values of resistors shown? With 43k ohms effectively in series for the base drive, it would be a very low current output from the transistor. The relay would need more drive current to energize. I usually like using a MOSFET for timing circuits, because they're voltage controlled rather than current controlled, and effectively open circuit inputs, so they don't draw any current from your timing circuits. That lets you use very small capacitors to get very long delays. I don't know why the 12V reference still shows a huge cap/resistor combination directly driving a relay for delay applications. It's much better to use a transistor driver for it, whether a bipolar or MOSFET.
