Dark matter with light mass represents a challenge for direct detection as typical kinetic energy can be below 1 eV.  However, in some rare instances scattering on very energetic solar electrons can bring the DM particles to keV kinetic energies, opening the way for probing these models using the largest and cleanest Xe-based DM detectors. I describe our calculations and numerical simulations of the reflected flux and derive novel limits on light dark matter scattering on electrons.
