1. A system for inspecting a railway track configured to adjust the intensity of a light emitting apparatus based on the motion of the system relative to an adjacent railway track wherein the system is mounted to a railway track vehicle, the system comprising:

  • a power source;

    a light emitting apparatus powered by the power source for emitting light energy toward a railway track;

    at least one motion detector for detecting the motion of the system relative to an adjacent railway track; and

    a processor in communication with the at least one motion detector wherein the processor includes an algorithm for adjusting the power of the light emitting apparatus, the algorithm comprising the steps of;

    a. determining whether the system is moving relative to an adjacent railway track based on incoming data from the at least one motion detector;

    b. adjusting a light emitter control output value based at least in part on incoming data from the at least one motion detector; and

    a controller in communication with the processor wherein the controller is configured to control the light intensity of the light emitting apparatus in response to the light emitter control output value.
