V photometric observations obtained at the 60-cm reflector of Shternberg Astronomical Institute Southern Station during July-August 1983 and WBVR photometric observations obtained at the 48-cm reflector of the Shternberg High-Altitude Station at Alma-Ata during September-October 1981 and October-November 1984 are reported for two WN stars associated with ring nebulae. The data are presented in tables and graphs and characterized. HD 187282 and HD 192163 are found to vary with amplitudes 0.04 and 0.01 mag and periods 3.871 and 4.554 d, respectively. Both stars are considered to be close post-X-ray binaries.
