I'm not sure you actually read what I wrote above. My batteries
were fine. The battery pack had defective wiring. That's a
quality control issue orthogonal to battery technology.

Mine are house shaped and I visited many electronics stores, not just Fry's,
when I was trying to make a replacement cable. No one had these connectors.

I'm sure the Niterider MiNewt is a great light. I do not like the idea of
using lights with proprietary batteries. What happens when the NR's battery
pack won't take a charge? Does it have to be returned to the factory for
service? I use a DiNotte 5W Ultralight, and when my rechargeable AAs stop
taking a charge I just pop for 10 bucks for new AAs. Plus, battery
technology is improving, so as rechargeable batteries get better my light
will get better. It shipped with 2300ma batteries, and now I use 2600s.

Does it really make sense to blind someone who's driving *towards* you?

I'm convinced that for moments, yes, you sometimes
need to blind the oncoming driver.

Of course, this is for different contexts: walking along
a dark road with no sidewalk (walking my dog) versus riding
a bike.

I've noted that drivers, even with a light shining in their
direction, too often do not slow down or swing wide of you.
You have to actually aim the light right into where the
driver's head/eyes would be in the oncoming car to get their
attention.

On a bike, you don't have quite the control of waving a
headlight around a windshield as you do with a hand held
light walking along a dark road.

Having two totally light blinded people heading towards
each other (at significant closing speed) isn't a good thing,
but I've become convinced that a few "blinding flashes" into
the operator's eyes is too often required to get a proper
response to your presence; and slow them down and give you
some space along the roadside.

I give up if they still don't get the message, figuring two
blinded people on a single road path isn't good. There are
some drivers who simply are not going to share the road with
you, whether you travel on foot on by bike on a road.

I'm not.

There are times you _may_ need to flash a headlight at them. I do this
with a "rock dodge" motion of the handlebar - but in my experience,
even that is probably unnecessary. I strongly believe that I'm more
visible at night than I am during the day. (And my daytime visibility
is just fine, thank you.)

But the post I originally commented on was advocating lights so bright
that other road users complained. Steady lights, not rare flashes.
That's about as sensible as constantly riding with a siren blaring.

I notice that when approaching an intersection where the majority of
drivers are turning left that they simply don't see a bicycle with a
low-power light, or if they do see it, they assume that it's moving very
slowly so that they have plenty of time to turn.

My recent commute had one of those intersections (El Camino and
Henderson in Sunnyvale). I'd be going south at a high rate of speed,
trying to make a green light, and vehicles turning left on ECR from NB
Henderson would not yield to bicycles with junky lights. With good
lights, they almost always yielded. They may have thought I was a
motorcycle or something. I don't think that I was blinding them, but the
two 14W lights were aimed such that I was definitely in their field of view.

In any case, a MiNewt isn't going to blind a driver. Maybe an HID light
could do that, but not a 4W LED light.

I have a NiteRider water bottle NiCad battery that works fine too. Its
from the late 1990s. No problems. No early failure. Heavy and big
though. I don't like the idea of a cord running from the battery on
the bike to my helmet light. One more thing to get tangled up.

Good for you!

You'll be squished in no time because a driver isn't forced
into thinking "what the heck is that?".

A small light glowing off the side of the road isn't enough
to get the attention of at least 50% of the cars I encounter
in my neighborhood (while walking myself and/or dog at night).

A brighter light that may be on a bike (3W and especially
10W and more) may be enough to get the attention of most
motorists.

My little ?? hand held light of perhaps 2.4W doesn't seem to
do it. I don't really even know if I'm blinding them, but
waving the light in the "eye area" does get their attention
whereas normal light on in front of you doesn't seem to do
much at all.

I think too often, motor vehicle operators do not respond to
roadside activity until they are directly upon it. Especially
if they are not certain what it is. Lights do not necessarily
cause a motorist to slow down, just like a sign that says "merge"
ahead doesn't cause everyone to begin the merge process.

Until a driver figures out exactly what that thing is moving
on the side of the road ahead is, they sail happily along
confident they can always stop or swerve as needed in time.

I've had to jump completely off the road too many times while
walking in the dark with a light passively at my side. When
I wave it across the windshield of the oncoming car, they almost
always start slowing or swinging wide.

Not a problem while riding a bike because you're in different
lanes, so blinding on coming traffic really has no benefit.
Only at or crossing intersections for the most part.

The same thing can happen from astern where motorists ignore
the red tail light until they're right up upon you. That is
why I have a pair of red tail lights (one flashing/one steady),
a reflective vest, reflective trouser straps and reflective
strips on the front and rear fenders. On top of that, my
panniers have reflective rear strips and my handlebar bag
also has one forward.

I am still sometimes on the very verge of bailing out off the
road when being approached by cars at night. Many just wait
until the last minute before acknowledging your presence.

I'd like to have a manually controlled strong beam to flash
in some motorists eyes behind me. I'm convinced they'd get
the message faster.

:) I'll be squished "in no time"? That would be very odd, seeing as
I've been riding at night regularly since 1977! Almost all of that has
been with a 3 watt generator light.

I'm always amazed that some people find the world to be such a
dangerous place.

My wife and I walk frequently at night. I do carry a light, since many
of our village streets have no sidewalks. But the light I carry is one
of those button-battery powered LEDs, roughly the size of three stacked
quarters. I don't remember any driver ever failing to notice it.

One tip: It's been shown that light sources (including reflectors) are
much more attention getting if they move, especially if they move in a
way related to a person walking. People are hardwired to notice other
people. So when you're walking your dog at night, turn the light on as
a car approaches, but swing your arm naturally as you walk.

On a bike, pedal reflectors produce this motion very well. Coupled
with a proper rear reflector and taillight, I doubt very much that
you'll have any trouble being noticed from behind. I certainly haven't
had trouble in nearly 30 years, and in fact I've gotten some
spontaneous compliments on my visibility from motorists.

Also, in the forward direction, you don't need much. Oncoming
motorists are in the opposite lane. The only ones that need to notice
you are those turning left across your path, and those waiting at stop
signs for a clear spot. A 3 watt generator light has always been
sufficient to get me noticed. In fact, I think any light bright enough
to show you the road surface is bright enough to be easily noticed by
motorists.

In fact, several times just this year I've seen that motorists making
those maneuvers waited overly long as I passed at night. That is, they
had _plenty_ of time to safely get going before I arrived, but they
waited patiently until I was past.

Don't tell me there isn't an element of danger in one of my
dog walk routes. I walk it extremely often, over years.

I don't feel the world is an exceptionally dangerous place
for walking or riding a bike. Generally people are pretty
good and other than encountering the rare psychopath on the
road, you'll be quite safe whether you even use a light at
all during the night, overall. People aren't out to kill
you.

But...

This stretch of road is wooded with turns; sparcely settled
with a town park where ball games run into the night and
some percentage of young people leave the part in varying
states of inebriation. Add to that, they go too fast.

You'd be a fool to just happily skip down the road in the
belief there is nothing to be concerned about because the
world is a very safe place.

Better drivers I guess. (I'm in Massachusetts).

I've come to the conclusions I have based on *years* of
walking that stretch of road. I obviously don't feel it
is so dangerous that I outright stay away from it, but in
the past I'd get pushed off the road by a driver coming
towards me (I walk on the opposite side of the road with
light and leashed dog) who simply is not going to share
the way with me.

I'm convinced, over years of experience on that stretch of
road, that just having the light on isn't good enough.
You need to wave the light right where the driver's eyes
approximately are to get his attention. Having the light
passively at my side facing down the edge of the road ahead
of me doesn't do it, and least with the hand light I use
which sounds pretty much the same thing you use.

I turn the light on, then wave it back and forth across the
approaching car's windshield. I have no idea if I'm "blinding"
him or not. But it does get his attention much farther out
from me than any other technique I've tried.

Pedal reflectors can't be seen too well from astern on my
bikes because of the panniers on the back. I'm not certain
how well they do overall as they are low and the pedal is
either angled down in parts of the pedaling motion, or are
overhung with the heel of your foot. I do occasionally
really notice pedal reflectors from off angles.

The wheel reflectors are good, but they don't help you much
fore and aft.

I have the 6V Dymotec generator on two of my commuting
bikes and am quite happy with them. I run 3W head lights
with AA powered tails. I think I'm well noted on the road
by motorists.

Given the lane difference between oncoming traffic on a
bike, blinding lights aren't so much an issue.

I agree that generally, at least around here, despite a
very high 18-25 year old male driving demographic, that
riding the bike on the road is very problem free. People
are quite good about giving bicyclists proper respect.

But walking seems quite a bit different, at least in this
one particular stretch of route I often use to exercise
myself along with a turbosupercharged Irish Setter!

Yup. I found them at Fry's in southern CA. Mar-vac had them too. If
there's a local electronics store like Mar-vac where you live, they could
probably order them for you. Or try one of the mail order catalogs.

I thought I still had some lying around, but I think I threw them in with
an old Nightsun set that I sold or gave away.
