I have been thinking. Early morning walking can be a bit hazardous. The danger comes when others hove into view and one cannot be sure that the oncoming has seen you. Now, at sea, at night, there are very definite collision avoidance instructions; you know red to red go ahead and other rhymes (red over red the captain is dead and red over green sailing machine). Don’t be fooled, there is nothing cute about these. They are intended to avert calamity.
My idea is to adopt nav lights for walking in less than optimal visual conditions. So, I would have a red light on my left shoulder and a green light on my right shoulder. To complete the ensemble, I would have a white light shining out my rear. This lighting configuration would signify a person walking at walking speed. When the person was of a younger ilk and was either scootering, running, jogging, skateboarding or in some other way being propelled along the footpath, they would have the same lighting configuration with the addition of an all-round white light on top of their head.
Now the Government needs to mandate this form of lighting to ensure safety on our streets. I will email the Prime Minister about this. I reckon it will be law by sundown; so, look out your lights.
