ive just put aux leds GTID etc
for the form factory i will buyis the lumintop fw3-fw21 pro (max size)
ive seen a little nitecore light with lcd screen and it looks so interesting, but the light is square, not sure if i love the style,maybe it could grow on me and ill order one
but the form factor that i love wouldnt take wifi , touch screen or make my coffee either
so for me
aux leds and gaskets!
Adjust / upload firmware wireless
Ooooh this has turned up to be interesting - I did think about adding more options, but though t it would be too much. Keep the ideas coming in here though hopefully now and again a flashlight manufacturer will look in! 
Integration in my hue home lighting. Aux lights signaling when the motion detectors in my garden detect something.
The best flashlight is spoiled if one dislikes using it. So, I’d like to see more lights with a good UI.
Direct to moon, direct to turbo, moon and turbo not in regular mode set, low follows moon. Sounds like Olight. Even better is a MCR. And that’s my answer: I want to see all sorts of lights equipped with a MCR. The lesser the additional space used for it the better.
More GITD options. I’d like to see “faux trits”, tiny tubular LED’s installed like trits. Of course, it would mean a path through the body for the wiring but as long as it’s potted that should be fine. Mini LCD display. So many variations are out now. I think they should be able to come up with a better symbolic lexicon to minimize letters. Remove language from the equation, just numbers & symbols. Battery voltage, estimated mAh, temperature, setting indicators, charging indicators, low batt…
Magnetic card reader?
Might be a bit cumbersome, though. Swipe for turbo?
I like to carry minimal tools when in the arcade,but one thing I could use (and pondered on making) is a light with a decent screwdriver in the tail.
I did find a cheapie one somewhere I was gonna ‘frankenstein’ into one (the driver bit) but it went by the by lol, The bits were too small really - but I think a regular bit would fit in the middle.
Somewhere I saw a photo showing the smaller driver bit holder, fitting into a larger regular sized one below it.
Yes, parental control. No?
Or maybe I’d like a magnetic control ring.
Aha, okay.
Kinda big for an EDC, but Sofirn/Wurkkos have a few magring lights. Discrete steps, though, not continuously variable.
The DV-S9, also kinda big, has a magslider which is continuously variable.
Discontinued, but price was not even $17 
Thanks for showing.
Huh… whaddya know.
Good thing I grabbed 3 of ’em when I had the chance. 
FT had ’em for 17 and change, same with GB.
BG had a goggle entry then plays dumb and makes like it doesn’t exist when you click on it.
I’ve been saying for a decade that I’d both personally enjoy and could use at work, a NC D11.2 using an 18650 and putting out 500 sustainable lumens of punchy” flood.
Not having that, I voted for Aux LEDs, mainly due to really enjoying them on the Emisar KR4 I’ve had for about a dozen days now. The Aux LEDs are not just pretty and enjoyable, I’m finding them practical as well.
I would like to see Anduril support NiMH and an easier way to keep all my lights (firmware) up-to-date; maybe via USB-C?!
I prefer a ‘regular’ no frills light. But it must be Hicri, with true IPX8 and works with button flat cell.
Unfortunately such lights are much more rare than frills light)
OLED display which can display the output, time remaining, colour temperature.
I think a simple OLED display could do wonders for a flashlight. Telling you the current mode/output level, temperature, and remaining battery would be great! Estimated runtime at current load would be interesting to have too.
I’d like to see a BLF light similar to an Olight S-Mini/S2 or ZebraLight SC64… pretty much as small as possible for a 1x18650 / 1x18350 light with a single LED and an e-switch. The focus would be on ergonomics and quality, like making it easy to carry and produce a neutral untinted white beam which isn’t too floody or too throwy. Output would probably range from about 0.1 lm to 1000 lm or so, though I expect it would probably only be able to sustain 300 or 400 without getting hot.
Of course, I’d want it to have an easy way to reflash firmware too.
Some sort of charging might be nice, though it isn’t necessary. Perhaps also a LED in the button capable of indicating charge level.
Overall though, designed to be nice but not very complicated.
TK, isn’t Lumintop EDC18 pretty much it?
