Also, the Reelights are practically useless off-angle (in candela):

As even 0.02 cd is not invisible (at night), you'd need much better accident
data to conclute that.

Vertical angle 0° Horizontal angle
−80° −20° 0° 20° 80°
Front light outer diode 0.02 0.22 4.43 3.74 0.05
Front light inner diode 0.05 0.59 5.50 2.15 0.05

Only salesmen (including guerilla marketing expert dimwits) would call a 5
cd front light DRL. Present DRL on Danish streets is described in UNECE
Regulation 87: more than a factor 100 more intense at 0V-0H.

To be fair, quoting Reelight's FAQ, some of their cr*p might have gotten a
bit brighter:
quote
Hub Lights with flash (SL100) emits 29 cd from the front light and 10 from
the rear light.

Hub Lights with ReePower (SL120) emits approx. 24 cd from the front light
and approx. 8 from the rear light.

The table doesn't even address vertical angle. I guess the cars are really
low to the ground in Denmark.

(It's those crushing Socialist taxes!)

Not only the cars are low, but Sun is low on the horizon. Luckily, if you
don't mind a bit of extra weight on your bike, Joerg will help you build an
extra strong flasher for your safety:
