I was on the back road coming home from a friend, so no street lights, and as I turned to go up the hill there, directly in front, were two very white and very bright lights, one over the other. The bottom one was steady, but the top one moved from side to side like an upside down pendulum
With it being dark there was no indication of how far away they were or whether they were stationary or coming towards me. Then as the road levelled off they flashed past and were gone.
What were they? A plane? A UFO? A spaceship? No! They were the LED helmet and handlebar lights of a cyclist and the idiot was in dark clothing.
Phew!
