The moral of this little story is that there is a danger in quoting
sources. Some rotten, no good, SOB, might read them.

Except that the Odense study compared two control groups. One with the
daytime lights, one without them. So each group had the benefit or
non-benefit of the various other changes you cited.


You really, really, should actually read the actually study.... who
was it that said something about engage the brain before activating
the voice?

Anyway, the actual study was not "One with daytime lights, one without
them" but between a permanently mounted and always on flashing light
and conventional bicycle lights. There was no indication of whether
the conventional bicycle lights were, or were not, used during the
daytime.

The results of the study was "The study contributed to a change in
Danish legislation whereby flashing bike lights became legal in 2005".

In short an always on, flashing, light, front and rear )that you can't
turn off (or forget to charge the batteries) is better than lights
that you can turn off or forget to charge.

The actual lights were the Reelight SL100 which is a permanently
mounted light mounted at the wheel axle level and powered by two
permanent magnets attached to the spokes.

Reelight states, "Reelight SL100 emits 29,000 mcd (microcandela, a
unit for measuring light) from the front light and 10,000 from the
rear light."
