Can anyone help all the lights work except for high beam on the o/s/f i have changed the bulb checked all fuses and even moved the relays around I have had a quick look at some earthing points.Has anyone had this problem or has anyone got any ideas I have a mot booked for next week thanks.

The high beam uses a H1 bulb in an adapter, there is a 3 pin connector on it that only two pins are used, the connector themselves often go green and become a bad connection, would unplug it again and check there for the condition and or for power with a test meter.
