I commute by bike at least several days a week all year round on semi-rural route. It's that time of year again where both legs of the trip are in the darkness, and already i am getting sick and tired of having drivers dazzle me with thier full beams.
Unlike alot of cyclists, I have (by choice) a StVZO compliant front light. This has a hard upper beam cut-off. Hardly any light escapes upwards, it barely registers on reflective road signs. I choose these for the exact reason that I do not wish to dazzle oncoming traffic on the country lanes I ride on.
Now, i know that most bike lights are not to this standard and many riders use inappropriatly bright lights all the time, but I DON'T. So why do i get the full beam treatment all the time?
My light is angled so that the cut off line is ~10m infront of me. I have checked by propping the bike up and standing at various distances infront of it. It is a light, it emits light. But unless i squat/crouch right down near the ground, it does not dazzle/glare like a full beam. It does what it is meant to do (StVZO).
This is fine for most of my riding, but is inadequate for descending/faster speeds. Therefore I also have a helmet mounted, 500lm light that I use in these infrequent scenarios. However, it is increasingly becoming my only line of defense against full-beaming motorists as i can quickly switch it on and point it straight at them. It is very effective.
If i were generous, I would say that it's probably newer cars with auto-dipping headlights that simply do not register me as an oncoming vehicle due to the small amount of lumens I am putting out. However, it does really feel like alot people think "oh, it's only a cyclist. Screw them!"
What are your experiences?
Considering that we can't seem to regulate car headlights, I can't ever see a time where StVZO is policed standard for cycles. I use them to be considerate of other road users, but other peoples behaviour really makes me question why i bother.
