Abstract. We study Schr\"odinger operators with a random potential of
Anderson-type. The single site potentials are allowed to change sign.
For a certain class of them we prove a Wegner estimate
(Theorem 5). This is a key ingredient in an existence proof of
pure point spectrum of the considered random Schr\"odinger operators.
Our estimate is valid for all bounded energy intervals and all space
dimensions.
