You asked for something more simplistic, see attached. It is essentially the same circuit. This is the first concept I thought of, but realized that I would have to change the Penlight battery periodically.
In this circuit you add more diodes in pink area to increase the voltage you want the battery to normally run at. Not decrease as in more complex circuit.
The regenerative input from break light doesn't have any delay to stay on. You can add a capacitor in parallel with relay coil to get some delay. The capacitor size will depend on your relay, so you will have to experiment with that.
I can't really quickly think of something simpler for you.
The only downside would be periodic battery changes, so I would recommend the more complex circuit for long term hassle free driving.

Thanks. I didn't mean I needed it simpler. I meant if you hadn't posted this, I would have made something more simplistic myself. But with you having done all the hard work, all I need to do now is copy it.
And that was
Gumby79's question involving 10v, not mine. He's got a pretty good nickname though.
