Went for a ride tonight and had two sets of bystanders at bus stops say: "wow check that out" and "wait I thought that was a motorbike"... It was a well lit road where I wouldn't need lights to see, not even most cracks in the road and it's a full moon... But again that's in the forward direction. I don't know how much light you get at 90%.
But to be fair bright lights are extremely rare here. Though they are slightly less rare than they used to be...
