Driver and momentary switch in the tail cap

I was givin a flashlight a little bit back and didn’t pay mind to it but it had a driver with 3 modes in the tail cap, single 18650 no batt carrier, no additional wires or extra tube for signal. Not sure how to post pics. Sorry

It’s possible to make a flashlight without any wires. Never seen a Maglite?? LOL

You can upload your pictures to imgur.com and post the links here.

it can be puled current to the LED that has bleeder resistors and then use them to charge cap and inductor for the MCU power supply
Imalent does it, but it has very bad runtimes in low modes and a very low PWM frequency
