"At Exposure, we feel it's as important to use good lights throughout
the day, as well as at night."

... um, because we're trying to sell the things, of course!

I don't use flash mode on my front lights though.

Then you disagree with the source you cited?


No. Those bright lights are visible enough in non-flash mode.

Speaking of visible enough: My wife and I just returned from a little
ride. We rode out to the suburban branch of our credit union to cash a
check, then a bit beyond it into sort of semi-rural roads. We returned
by different roads. We were on some quiet residential streets, some
former farm roads that are now short cuts to housing developments, a bit
on an arterial road or two with 50 mph traffic, etc. Quite a few miles
were on lanes that were obviously too narrow to share (like 9 feet wide)
so we rode at lane center.

As usual, we had no problems with any drivers. (Well, except a couple
who were clogging things up while they seemed to be looking for
entrances to some obscure businesses). And there was absolutely no
indication that anyone had any trouble seeing us.

Apparently, we were visible enough. Our bikes both had dynamo powered
lights, but neither of us had them on.



Some people are not so lucky in the lane.

You can find videos of almost anything on the web.


It's called facts. Two university mates of mine were rear-ended in the
lane. One lost a kidney, the other had a ruptured spleen. At least in
one case the driver stuck around, something that doesn't appear popular
anymore these days.


It's called anecdotes. You searched a world-wide source and found three examples, each on a separate continent. You tell us about two friends, but I file that in the same drawer as mountain lion attacks, chain repair using rocks and found nails, and your many miraculous escapes by your other super-wise equipment choices.

You offer commercial advertisements as evidence that daytime lights are absolutely necessary, and you offer anecdotes as evidence that leaving the gutter is dangerous. Why not look at cycling education documents like _Street Smarts_ or _Cyclecraft_? Why not look at educational programs like "Cycling Savvy" or "Smart Cycling" or "CAN Bike" or similar programs in other countries?

Permission to stick head back into sand granted.


Annual U.S. deaths: Motorists, over 40,000. Pedestrians, over 4500. Bicyclists, only 800 in a bad year. Pedestrians are three times as bad as bicyclists per mile traveled.

What lights do you carry when walking in daylight? Or are you sticking your head in the sand?
