Ok don't try and turn the lights off while on main beam, I tried on our farm track ( to see how bright the LEDs are) and found the stalk won't turn back if your in high beam, so I turned and turned a bit more, thinking this isn't right. Almost snapped it off, !!!!! And pulled to dipped and of could it turns, silly me,,,,,, anyway on a very dark farm track LEDs are great lol
