Abstract

Contact binaries can be used for distance determinations of stellar systems. They are easy to discover and identify and are very abundant among solar-type stars, particularly for M_V > +3. The period - luminosity - colour (PLC) relations have similar properties to those for pulsating stars and can currently predict individual values of M_V to about +/-0.25 mag.
