I have a flashlight with a strobe mode and need to know how to slow down the strobe on it. Please tell me if I should add a resistor or vary the power source to slow and NOT dim the strobe light.

  • \$\begingroup\$ A very hand wavey question. But the answer you're looking for is: you need to reprogram the micro controller that is in the device. \$\endgroup\$

I don't think that is possible, since these kinds of functions on flashlights are usually controlled by microcontroller and not by discrete electronics. At least I have never seen one where that was the case.
