Saw this under new items at KD today. You have to buy five at a time, but it looks like it could be a good option for people with AA lights that have died and you can't use a 17mm board.

Description says for AA/AAA. It is impossible to fit in an AAA because most AAA use 10mm ones.
Also it could arrive as a single unit not 5 pcs pack
However, good tip!
KD does themselves no favors by providing so little information. It doesn't say what the 5 modes are or whether it can be used with lithium-ion cells. And, I agree that there are not many AAA lights that will be able to use this driver and only the pictures indicate you will actually get 5 pieces instead of 1.
Of course you get 5! KD may have rubbish descriptions etc. but when KD says "5pcs bla" it means they ship 5pcs.
Could be good to upgrade Tank 007 E07. Inside diameter of the led/driver assembly is 13.05 mm, so with a little bit of sanding this one could fit. Ordered anyway.
