High Viz
Invisible man with low status
I need to be seen during poor lighting or weather conditions
Too retroreflective stripes
Helps to distinguish between objects and people
Work and cycling
A substance that has absorbed light
Emitting light
Still shining more in the moonlight
Than in the daylight
More easily discernible from the background
When in environments where there is a lot of moving machinery
Chartreuse yellow is a nice colour
