low beam trouble, Berlingo 2006

[Kieron G]

Although the relay(s) click they might not be making a connection on the main feed to the lights. It sounds to me like the switch side of the circuit is working but the main live to the lights is not getting through. With the fault having been intermittent it sounds like it could be a relay. I don't know where the fuse comes in the circuit but you can check if there is a live there just by going from the live side to earth with a test light.
