I am trying to work out a way to increase the light intensity with a
dial for a regular LED from a dollar store flashlight. I don't know
much about the LED since I can't see any markings.
What would I need to buy from Radio Shack or an electronic store to do
this?

Thanks

You could buy one of the dollar stores lanterns with a variable output, and transfer the ckt.
Its not going to fit inside the flashlight, but you might be able to size down the ckt.
