Embodiments described herein include a portable system for providing lighting, the system includes a power source that comprises multiple electrical power storage cells in an array that is articulable such that the array is attachable to irregular surfaces, and non-planar surfaces. Embodiments further include a light source coupled to the power source, a primary light beam shaper that shapes light from the light source and passes the light to a lens, and a housing that houses the primary light beam shaper and the lens, wherein the housing is a secondary light shaper that changes the field and shape of a light beam emitted from the primary light beam shaper. Further embodiments include an automatic, powered portable light that is turned on when motion is sensed, such as deceleration of an object. The portable light, a switch and a power source are contained in a housing that is easily mounted to an object such as a bicycle.
