I THINK I've got it:-
I thought about lowering the value of Rs, Nick, but that's the only 1Ω resistor I've got, and none smaller.
Off-load there's 1.5V across the LED and on-load 1.7V which is enough to light it. A high intensity type would be better but the only ones I've got are white which I'm not keen on as indicators.
The next question will be if a properly soldered-up version works.
