Abstract
A light emitting diode (LED) flashlight that utilizes reflection techniques to maximize light provided by the one or more LED light sources. A reflection housing is connected to the flashlight housing and includes a light housing that is suspended within the reflection housing and positions the LED light source toward the flashlight handle. Reflective surfaces within the reflection housing receive the light emanating from the LED light source and reflect and re-direct the light out the transparent end opposite the flashlight handle.
