Now, if you've got quite a posh cycle light, the chances are it will have a shroud over the top of the front light, so you probably don't need to worry.
But if you've got a flashing front light with no shroud, cycling down a dark lane can be quite scary, however, bright your light is.
The problem is that your eyes can't adjust to the sudden change between light and dark and you are partly dazzled by the backlight. In fact, recently we've been out in some country lanes a bit late coming back and ended up turning the front light off and navigating by the moon, getting ready to switch it on quick when we saw a car approaching in the distance.
The flashing is still a bit of a problem though - your eyes still find adjustment a bit tricky although its still needed for safety.
Perhaps the full solution is to have the flashing on top of your head to be seen and a steady fixed light on your handlebars for you to see.
Then all you've got to worry about is being reported as a UFO.
