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.
