Remote switch for Fireflies E07

Some months ago I bought a Fireflies E07 flashlight which I use for cycling. It is awesome!

The only problem is I mount it under the GPS mount and the switch is quite difficult to use from the handlebar. I change modes quite a lot (high on the descents, medium on flat, low on the climbs or in main streets with plenty of light)

Is there any remote switch I could use or adapt to this flashlight?

Is there any other flashlight for 21700 batteries (not integrated) similar in performance to the FF E07 with a remote switch?

You could get the switch PCB out and solder to the leads to an external switch with leads, then glue the switch hole with some silicone on the flashlight

When I bought the E07 I also bought a F01, which was faulty so they sent me another one for free.

BTW It took a while but the response was very good.

I disassembled it to see if I could fix it but eventually I couldn’t, I didn’t have a multimeter or any other specialised tool here where I’m living now so I just forgot about it.

BTW It came with plenty of thermal paste

To the point… the button on the F01 and E07 is the same and it’s mounted in the same way. I tried to take it out (from the broken F01) by prying with a sharp knife on the button bezel and it is impossible! From the inside the button sits just in the middle of the front and middle compartment, so no access either.
How do you do it (without breaking it)? :S
