An illumination apparatus for a winch configured to engage a retractable cord is disclosed. The illumination apparatus comprises a light source configured to emit an excitation emission at a first wavelength. The excitation emission is configured to activate an illumination of at least a portion of the retractable cord. A first photoluminescent portion is disposed on the retractable cord and configured to emit a first output emission having a second wavelength different from the first wavelength in response to receiving the excitation emission. The first photoluminescent portion may serve as a marker or visible notification of a position or portion of the retractable cord.
