Such elevator systems may be associated with or located within wind turbines and wind turbine towers. In embodiments, an elevator cabin may comprise a dual source light system further comprising at least one light source, a supercapacitor unit, an electronic circuit electrically connected to the at least one light source and the supercapacitor, and a housing unit. The dual source light system can receive energy from an external power source, convert one or more characteristics of the energy, e.g., voltage or current, and distribute the energy to the at least one light source. Any excess energy can be used to charge the supercapacitor such that when energy from the external power source is insufficient to power the at least one light source, such as during an outage, the electronic circuit draws energy from the charged supercapacitor. ## Claims ### Claim 1 An elevator system comprising: an elevator cabin within a wind turbine;
