1. A self-powered illumination assembly for a vehicle, comprising:

  • a microelectromechanical systems (MEMS) array connected to a vehicle structure and configured to convert vibration energy to electrical energy, the MEMS array including a plurality of sensors configured to harvest vibration energy from a plurality of frequency ranges, at least one sensor being configured to be responsive to a first vibration frequency bandwidth and at least one other sensor being configured to be responsive to a second vibration frequency bandwidth different from the first vibration frequency bandwidth;

    a storage device electrically connected to the MEMS array to store the electrical energy;

    an illumination member electrically connected to the storage device; and

    a proximity sensor connected to the MEMS array, the stored electrical energy being supplied to the illumination member by the storage device when activated by the proximity sensor.
