Abstract
Abstract A headlamp cleaning device for a vehicle having a twin headlamp system comprises a pair of spaced, parallel actuating rods and a pair of spaced wipers extending between the actuating rods and attached thereto. The actuating rods are slidable in bearings resiliently mounted on the body of the vehicle so that the headlamps are not obscured by the rods. The rods are reciprocated by a common drive and the wipers are arranged so as to be parted off the headlamps when not in use.
