Chapstick diameter light w/ tail switch (push button)

[lumen aeternum]

Got a plastic thing for the car that holds a chapstick, the package has two so I want a light to put in it. The control stalk for the lights is hidden behind the wheel & the interior lights don't illuminate it. Sometimes I want to check the function setting. Needs a button on the tail so I can use it one handed. I suppose red or green would be nice instead of white, which is probably too bright.

Looking at the online specs for a tube of Chapstick, it appears to be 15mm in diameter. Most AA or 14500 lights would be too thick. Triple A and 10440 lights would fit the bill. Looking at a Reylight Pineapple Mini, it’s listed with the head and tail at 15mm, with a smaller diameter in the middle. The “Cylinder” variant seems to have a straight-sided, same-diameter body.

If you email Rey, he will be able to provide exact specs and maybe even make a custom light with your preferred emitter color.
