Re: The single AA dual mode light is ignored
I have contacted several modders again. I tried the same last year with no response. "nailbender" may very well have the key part of the solution in his very fine looking custom drop ins...we are discussing that now. He has one on the boards tuned just for a single AA. If it will work, just as you have illustrated I will just need to sort fitting the battery in the E2E tube and figure out switching. I hope it turns out that simple and if so I will likely buy more than one.

The OP has specified a very precise requirement, and it is a very interesting one IMO. Members have made some interesting and helpful suggestions, but the OP is perfectly entitled to decline them if they do not meet his requirement. This thread is almost a challenge to this board to see if we can arrive at a solution, and (to me, anyway) that is part of what makes CPF the great forum it is.
The solution will most likely be in 2 parts. KeyGrip seems to have got closest to it.
The first part involves modification of the head (and possibly the tailcap too). This job has Milkyspit written all over it - he does Custom jobs like this the whole time. PM him with the details, and ask him what he needs. He'll probably tell you to send him an E2e or E2L so he can mod it for you.
When he has done it, you'll have a light that does what you want but has a body tube that is ~17mm too long for an AA cell. You can use a 17mm spacer, and wrap the AA cell in paper to stop it rattling, or you can go to step #2 - to make the tube the right size.
For that you'll need an after-market replacement tube (some suggestions have been made) or alternatively you could send the tube off to be shortened from 67mm to 50mm and re-threaded. There are plenty of people who could do this work for you - many of them hang out here in MMM. Send a PM to a few of them and see who responds.
