What is a dynamo powered flashlight? Since you contrast it with a battery powered flashlight it sounds like a flashlight that gets its power from a dyno? You pedal the bicycle to make it produce light? Like a headlight presumably. What is it in your car for? If you "need it" then what do you do with it?
