Does anyone know how to adjust the brightness for this flashlight? It was adverised as having 3 levels of brightness ( Medium / Low/ High ), but mine only does on/off.
MrTomahawkFrom personal experience, I expect that the top of the flashlight was already screwed on tight when you first put the battery in. Then it would have lit up immediately as soon as the bottom cap was screwed on to seal in the battery. You need to securely tighten the bottom cap, then loosen the top one. By the way, when the top cap is loosened just enough for the light to go out, you can then preview the different brightness levels by simply squeezing the whole flashlight, top to bottom.
