  We present the results of our survey searching for new white dwarf pulsators
for observations by the TESS space telescope. We collected photometric
time-series data on 14 white dwarf variable-candidates at Konkoly Observatory,
and found two new bright ZZ Ceti stars, namely EGGR 120 and WD 1310+583. We
performed the Fourier-analysis of the datasets. In the case of EGGR 120, which
was observed on one night only, we found one significant frequency at 1332
microHz with 2.3 mmag amplitude. We successfully observed WD 1310+583 on eight
nights, and determined 17 significant frequencies by the whole dataset. Seven
of them seem to be independent pulsation modes between 634 and 2740 microHz,
and we performed preliminary asteroseismic investigations of the star utilizing
six of these periods. We also identified three new light variables on the
fields of white dwarf candidates: an eclipsing binary, a candidate delta
Scuti/beta Cephei and a candidate W UMa-type star.
