Ignition switched on dipped lights are on. Move light switch from off to side and correctly side lights on. Move to headlights okay both dip and main but switching light switch off dip beam remains. The light switch itself seems okay after removing and checking on bench. The relay appears okay after checking on bench and seems to click as expected.(It is a double relay combined in engine bay.) Removed adjacent box for warning of bulb failure giving only side lights and also small black box forward of main double relay. NO improvement. Is this a problem with stalk which works correctly? ( As I see it a feed from ignition on is getting into dip beam circuit) Anybody any definite pointers? N-reg aero.
