Nice shadow you're casting there. I presume you ride with a front flashing light on your bars so that you can be seen through the sun glare behind you
Not a flashing light, but I have a permanent headlight powered by a generator.
light for you to see wit
light for you to be seen
when you ride out of a rising sun, or away from a setting sun the sunglare behind you renders you invisible to oncoming traffic and traffic turning out of side streets ahead
a bright flashing light appropriately positioned (pointing forwards to be seen not down at the road to see with) on the front bars provides a contrast against the sold block of your body behind the light.
oncoming/turning traffic can see your flashing light out of the solid block behind you, a solid light is nowhere near as recognisable and can be easily (and often) missed in sunglare - it is the contrast of the flash on/off that is seen, a solid light does not have this contrast to be picked out easily
there's videos on youtube that show this
another ready example you can see yourself is when you are travelling in the opposite direction and cars are blocked from view by sunlight but then indicate to turn and you see their indicators. sunglare renders vehicles invisible, it does exactly the same to cyclists.
When you see vehicles in sidestreets waiting to turn and the driver has their hand up shielding their eyes from the sunglare... another example of where a front flashing light increases your chances of being seen
often hear "but it was broad daylight, couldn't they see me"
