Thank you!
Following your post I double checked the battery connections, and found I had missed a small lead off the negative terminal when replacing the battery after recharging (during the day) - it had fallen down behind the wiring!
Result - Main beam warning light now out when lights on, ( unless on main beam on of course ) and no buzzer sound coming from the dash!
