It’s larger than 6 of the lights in my pic and that is far from a comprehensive list.
An AAA cell an led soldered to positive contact thin wire wih resistor to negative
Won’t work, even a red LED needs 1.9 Volts.
as far as being longer than 6 other lights, how many of those are tail-button lights?
of course twisties are shorter but i hate twisties

Two. The Tool Ti & the Streamlight/ITP lego.
That being said, let’s not forget that the original question wasn’t “What is the smallest/lightest tail switch AAA”. 
ok, i don;t care any more… it;s short and small and cheap and has a tail switch and it works well
