My experience is clearly different.

Your experiences are almost always unique, not just
different.


Yet strangely, it jibes with that of our government folks.
Why do you think they mandate DRL on motorcycles?

And yet motorcycles are the one category of MVs in Oregon
with increasing fatality rates. e.g.
http://www.eastoregonian.com/eo/loca...king-this-year






You of all people, having been an amulance driver, should know the
reason. The reason is this behavior:

https://www.youtube.com/watch?v=ZkWWVryT1UE

That is the road where I was almost clipped by a motorcyclist.
He didn't anticipate that there could be a mountain bike in a
right turn, hugged the curve at high speed and ... "GAAAH!". I
heard his engine screaming but didn't have anywhere to go
because of a wall of rock to my right. He needed the full
oncoming lane to get the situation somewhat under control.
Imagine what would have happened if there'd been oncoming
traffic.

Did you have your super-bright light on?


Of course.


... Did it prevent the motorcyclist from being an asshole? If
not, you need a much brighter light. You need the Asshole
Eliminator from Magicshine -- 60,600 lumen high rate flasher.
Run it all the time.


The light is for regular straight stretches of road, it won't help
in tight curves. Though it might cause motorists to recognize me
fractions of a second earlier.


Then why are you telling us the motorcycle story if it is not to
illustrate that bright DRLs are needed? If you just want to talk
about assholes in cars or motorcycles, that is rather mundane and has
nothing to do with lights.


sigh

I bring these examples to show just _who_ is on such roads. Drivers that
are reckless, inattentive, incompetent, slow in reaction speed, soused,
stoned, or all of the above.


And your post about being seen by on-coming, passing cars on straight
stretches, you seem to confuse being seen with playing chicken. I
ride on country roads all the time where cars in on-coming traffic
get into my lane to pass. They can see me. I'm looking right at
them. They just don't care. Being that I'm not riding a 3 ton F350, I
pull to the right. A magical light doesn't change that dynamic.


It does because I notice that with the light on fewer people attempt
such maneuvers.


I did a short ride today -- my legs are killing me, and I haven't
been off my bike for weeks. It's overcast and rained this morning. I
saw maybe thirty other cyclists on my little climbing route -- maybe
two with DRLs. No deaths to report. No breathless hysterics,
stranded people, incompetents with exploded tubeless tires. Totally
normal, at least by Portland standards, which for you might be super
scary since I'm riding on city streets at full speed! Eeek!


I hear a lot of cyclists saying the legs hurt. For me it's never the
legs, those are always fine. I run out of breath and become generally
exhausted on long hilly rides. My legs could go on another 50mi but the
rest of my body doesn't want to.


Maybe it’s the beer and sandwiches you use for nourishment on those
rides...

Since I'm a mechanical guy, not an electronics guy: Both of those seem

chance of getting you to explain what they do?

I had an off-brand LED dynamo light fail on me. The LED fried itself. In
the course of replacing it (which was difficult because of the lack of
wowrking space) I was able to take some guesses at the function of the
circuitry components - rectifying, regulating, etc. But there were only
about six or eight electronic devices in there. I'm surprised a DC
battery lamp needs much at all.

Repairing a car, TV, radio, mower, phone, etc.,

Good luck finding such a shop today with
a couple of guys being able to do all that with

The other problem, in America at least, is the high cost of skilled
labor vs. the low cost of complete repair.

Example: I've got a CD player in the kitchen that has gotten unreliable.
It's unable to play some commercial CDs at all, and it has a hard time
finding Track 1 on others. (For some reason, it will play OK if I tell
it to jump to track 2.) And it has no hope playing most CDs I burn myself.

I opened it, checked for sticky rails, cleaned lenses, etc. but found
nothing. I took it to an electronics repair place, and the tech guy said
"It will cost you $80 minimum for me to just look at it. You're better
off buying a new one."

I've got a grandson who is VERY interested in taking things apart. He
actually asks me to bring over stuff that we can disassemble. (Yes, of
_course_ we've done a clock!)

Granted, some of his computer disassembly was done with a hammer, but
that's OK. I want to nurture the curiosity.

My favorite photo of him was taken when he was one year old. He couldn't
yet talk. But completely on his own, he grabbed a phillips screwdriver
from his dad's tool box, toddled over to his cousin's bike, plugged the
screwdriver into a phillips screw on the bike and tried to loosen it. I
snapped the photo and still have it on my refrigerator.

Thanks to all the gods. 6500 lumens! I think you can have either
5000 or 1500 or all 6500 lumens. Thankfully now we will not only be
able to blind everyone else on the road or trail, but we can now
cause their eyeballs to burst into flames and maybe hopefully their
heads will also explode. Yeah!!!!!!


This one for their rear light is weird, quote "A sleep mode is
triggered after one minute of inaction to save power, any vibration
will immediately re-activate the unit".

So the light will go out while waiting at an intersection? Really?
Nobody raised their hand during the design review? Was there even a
design review?

First, their definition of "sleep mode" may not be "goes out." It could,
I suppose, just become much dimmer. In any case, it would be easy enough
to jiggle the bike a bit to turn it back on.


Not very smart on the part of the design engineers.


But it's probably not necessary. Ohio law specifically permits lights
that go out when the bike is stationary, ...


Not a smart decision by the lawmakers.


... and there's never been a report
of a death or serious injury caused by that feature.


Grandpa drove without a seat belt all his life and never go hurt, so ...

Grandpa also rode his bicycle without a six foot tall safety flag, a
siren, a bell constantly and automatically ringing every time he
moved, pads on his knees, pads on his elbows, body armor protecting
his spine. Why are you not using all those measures?

(Actually, maybe you are. With you, we never know.)



BTW, it even happens from the front, even by police officers:

https://fox2now.com/2018/07/30/polic...hone-in-video/


Nothing can replace bright light other than even brighter
lights. Which both of my bikes have.

Joerg, you're the master of the worldwide search for the vanishingly
rare exception. That is NOT a common crash type, as any dispassionate
search of the literature would shoe. And you have no evidence that
your daytime headlight would have prevented it.

Looks like the video has been taken down, at least fox2now.com can't
find it.


Works fine here.

Works for me now, no more "video unavailable".


... The accident happened in broad daylight, no vehicles save the
cop SUV and the cyclist visible for miles, cyclist waiting at an
intersection, I think for a stop sign. Total f*up on the part of the
cop, who was more or less apologetic. A daytime running light would not
have helped.


Not true. I clearly found that drivers notice me much better with
bright lights. Even in the corner of their eyes is enough because it
"distracts" them in a good way. All it takes is noticing a cyclist a
second or two earlier and a collision can be avoided.

Seriously? The cop would have looked up from his phone if only the
cyclist had had a light? Sounds like magic.


Easy to try. While distracted with some chore in your home, have
someone walk towards you pointing a bright but not blinding LED
flashlight. It works. A human eye is not insensitive in the directions
where one does not look, just less sensitive. The "muffling effect"
needs to be overcome and intense light is just about the only method
to achieve that.

This wasn't inside, it was outside in bright daylight, looked like
hardly a cloud in the sky.


Try this in daylight. It works.


... A really bright light is required to make much difference
in that case.


Bingo! Now you know why I have bright lights on my bikes. I experienced
it again yesterday. I had to ride through city streets for many miles,
partially at max speed. With the light fully on nobody cut into my path.
Without lights that is different.


Other clue: You are driving a car, looking ahead into traffic as you
are supposed to do. The dashboard becomes largely unnoticed except for
the occasional glance at the speedometer. However, when the yellow
check engine light, the red oil pressure light, the overtemp light or
the low fuel light comes on it is immediately noticed. Same if someone
behind you flashes their headlights even while you aren't looking into
the rear view mirror.

That only happens if you have the habit, perhaps not completely
conscious, of scanning the dashboard. How do you know it's "immediate"?
You notice it when you notice it, and if it's 10 seconds after the event
that's not a big problem, unlike the case for traffic on the road.


If bright enough or if a less bright light in flashing mode I see that
immediately. An airline pilot could even lose his license if he didn't.

If bright enough... that is exactly what I said, isn't it. But a great
many cars do not have bright warning lights.

As for airline pilots... I can't speak for the airlines but USAF
bombers have a very bright master warning light located at eye level
on the instrument panel that comes on if any of the individual warring
lights are illuminated. See
https://en.wikipedia.org/wiki/Annunciator_panel

"More complicated aircraft will feature "Master Warning" and "Master
Caution" lights/switches. In the event of any red or yellow
annunciator being activated, the yellow or red master light, usually
located elsewhere in the pilot's line of sight, will illuminate. In
most installations they will flash and an audible alert will accompany
them. These "masters" will not stop flashing until they have been
acknowledged, usually by pressing the light itself"


You have exactly described what I mean. My front annunciator to car
drivers is roughly in their line of sight and very bright. The rear one
isn't so bright put pulsates. Not irritatingly but gently dimming up and
down in random fashion like police cruiser lights. So even if drivers
are distracted and glancing over to a GPS screen or cell phone they
notice. Which is all I want. It works.

A small price to pay for safety. I've got less than $50 worth of
material in there and the total weight is around 1lbs due to a fairly
large Li-Ion battery. That on is only large on the road bike, for 4-5h
rides.


"A small price to pay for safety"?

You mean that after having spent only $50 you are now totally safe?
The mountain lions and the milk cows can't harm you any more?

EVERY superstitious "safety!" gizmo is touted as "a small price to pay
for safety." That's been said of bike helmets, hi-viz clothing, daytime
running lights, air horns on bikes, six-foot tall flippy flags, lateral
flippy flags, leg lights, laser-projected bike lane markings, elbow pads
and knee pads, bike turn signals and more.

Meanwhile, study after study has shown that the benefits of bicyclng
greatly outweigh its tiny risks. IOW, riding a bike is literally safer
than NOT riding a bike.

I wish you'd switch to burdening pedestrians with your crazy "safety"
ideas. 4500 fatalities per year. Something must be done! And you can
make a profit by selling them junk!


A few years ago the CHP did a study of bike-auto collisions in Los
Angeles County and found that more then half the accidents were the
fault of the cyclist and I recently read a DOT study that showed that
20% of the cyclists that died in an accident had been drinking alcohol
it would seem that bicycle safety is largely a matter of the cyclist
his(her)'s own actions rather than the brightness of his(her)'s
driving lights.

Yet another one: Think about the reason why approaching emergency
vehicles have very bright flashing lights.

Now imagine all of these riders with lights and sirens:
https://d3n8a8pro7vhmx.cloudfront.ne...png?1428427634

This is the daily commuter traffic into downtown. Now put all those
people on the two-way cycle track on my way into work.
https://bikeportland.org/wp-content/...ansit-bend.jpg
Now live with that.


As I've written several times, bright lights are not needed on bike
paths. I turn them off there during the day. They are also not needed
when there are lots of cyclists (safety in numbers). It's different out
here, this is not Portland, Amsterdam or Copenhagen.


Solid white lights in bright sunshine are almost universally
irrelevant and annoying to other cyclists and drivers.


No, they are not. Why do you think motorcycles have mandatory DRL? Just
for fun?


... I see jerseys
and body shape long before I register the light.


That is totally contrary to my experience and that of just about anyone
I know.


... And BTW, having
driven ambulance for six years, I spent plenty of time sitting behind
cars with my deafening Federal Q2B pegged before the dopey driver
turned down the music and realized I was sitting there -- and then he
freaks out, hits the gas, goes into the intersection and gets
whacked. It can be a sh** show. Whatever giant light, siren,
calliope, marching band you claim will save your life can only make a
marginal improvement and proving that margin is hard if not
impossible, and a blinding light can cause accidents or at least
upset.


That driver shouldn't have a license.


What will really reduce accidents is being a good rider and knowing
how to ride in traffic and with entering or exiting traffic.


That's the problem. A lot of car drivers do not fall into that category
and that is beyond my influence. What I can influence is how my ship is
lit, so I do that.


No you can't. Marine vessels must adhere to very stringent
international regulations for the lights that they display and the
brightness of those lights.


I tend not to operate marine vessels on roads and bike paths. They'd get
scraped up too badly :-)


But you are the one that mentioned "my ship".

You mean that after having spent only $50 you are now totally safe?
The mountain lions and the milk cows can't harm you any more?


I linked earlier to the guy wearing a safety jacket similar
to Jay's:

The shooter got away SAFELY on his bicycle, due at least in
part to his magic garment. Hi-Viz saves lives, even if
sometimes the lives of murderers. Magic, in its literary
form anyway, tends to create plot turns like that.

My experience is clearly different.

Your experiences are almost always unique, not just
different.


Yet strangely, it jibes with that of our government folks.
Why do you think they mandate DRL on motorcycles?

And yet motorcycles are the one category of MVs in Oregon
with increasing fatality rates. e.g.

You of all people, having been an amulance driver, should know the
reason. The reason is this behavior:

https://www.youtube.com/watch?v=ZkWWVryT1UE

That is the road where I was almost clipped by a motorcyclist.
He didn't anticipate that there could be a mountain bike in a
right turn, hugged the curve at high speed and ... "GAAAH!". I
heard his engine screaming but didn't have anywhere to go
because of a wall of rock to my right. He needed the full
oncoming lane to get the situation somewhat under control.
Imagine what would have happened if there'd been oncoming
traffic.

Did you have your super-bright light on?


Of course.


... Did it prevent the motorcyclist from being an asshole? If
not, you need a much brighter light. You need the Asshole
Eliminator from Magicshine -- 60,600 lumen high rate flasher.
Run it all the time.


The light is for regular straight stretches of road, it won't help
in tight curves. Though it might cause motorists to recognize me
fractions of a second earlier.


Then why are you telling us the motorcycle story if it is not to
illustrate that bright DRLs are needed? If you just want to talk
about assholes in cars or motorcycles, that is rather mundane and has
nothing to do with lights.


sigh

I bring these examples to show just _who_ is on such roads. Drivers that
are reckless, inattentive, incompetent, slow in reaction speed, soused,
stoned, or all of the above.


And studies have shown that cyclists who are involved in accidents are
likely to be "reckless, inattentive, incompetent, slow in reaction
speed, soused, stoned, or all of the above."



And your post about being seen by on-coming, passing cars on straight
stretches, you seem to confuse being seen with playing chicken. I
ride on country roads all the time where cars in on-coming traffic
get into my lane to pass. They can see me. I'm looking right at
them. They just don't care. Being that I'm not riding a 3 ton F350, I
pull to the right. A magical light doesn't change that dynamic.


It does because I notice that with the light on fewer people attempt
such maneuvers.


I did a short ride today -- my legs are killing me, and I haven't
been off my bike for weeks. It's overcast and rained this morning. I
saw maybe thirty other cyclists on my little climbing route -- maybe
two with DRLs. No deaths to report. No breathless hysterics,
stranded people, incompetents with exploded tubeless tires. Totally
normal, at least by Portland standards, which for you might be super
scary since I'm riding on city streets at full speed! Eeek!


I hear a lot of cyclists saying the legs hurt. For me it's never the
legs, those are always fine. I run out of breath and become generally
exhausted on long hilly rides. My legs could go on another 50mi but the
rest of my body doesn't want to.
