    Abstract: Apparatus for washing and wiping both windscreens and headlamps of automobiles comprises windscreen washer and wiper motors, headlamp washer and wiper motors and control means. The control means includes a transistorized switching circuit whose switched state is governed by the charged state of a capacitor. This switching circuit controls, through a relay, the operation of the headlamp washer and wiper motors such that when the headlamps are switched on they are washed and wiped for a predetermined length of time and so that when the windscreen wiper and washer motors are operated, if the headlamps are on the headlamp washer and wiper motors are automatically operated too.
