[net.misc] highway lights peculiarity

dir (04/05/83)

Has anyone noticed while driving along the highway at night
that a highway lamp will suddenly go out while you are approaching it?

I estimate that I see at least one lamp go out every time I drive at night.

Question: Given that lamps burn out, what's the probability
          of coming upon a lamp as it goes out?  Is it possible to
          get a reasonable estimate of this probability?

I bring this up mainly because I have found it odd to be driving along
and suddenly see a highway lamp go out as I come upon it.  Seems
to happen more often than one might expect, but I haven't studied
the probabilities.

I don't know about lights going out as I get near them,
but I do know that a similar phenomenon occurs with
traffic lights, which go from green to yellow to red
at my approach.

I too have noticed this sort of outage over-occurance on the highway
(and on campus too, where those types of lights are installed).  But,
with the campus lights, I've found that they come back on in a minute
or two.  This has led me to the theory that these types of lights op-
erate at high temperatures, and thus turn themselves on and off to
avoid nasty happenings, such as explosions.

Is Reddy Killowatt out there?  Can anyone verify this?

I can't say i have seen highway lights go out as
i approach them, but i have certainly noticed a 
similiar, perhaps related phenomonon with refrigerator
lights.  perhaps a qualified paranormal investigator
can enlighten us.

I've also noticed street lights to go out when my car approached, but had
guessed that it was a result of my headlights triggering the day/night sensor
which turns them off/on.  During a thunderstorm lightning will sometimes
do the same thing.  Any better ideas?

I once noticed a lamp go out, fall off, and smash all over the street
once when a vehicle that I was in backed into its supporting structure.

Some highway lights are controlled by photodetectors which
are supposed to turn them on at dusk and off at dawn.
Maybe perhaps one of your headlights is pointing rather
higher than it should???

  There is a streetlight near here that often seems to be going out
just as I arrive under it on the way home.  I thought it might be
the lights from my car on a photo sensor, but it is too high up for
my headlights to hit it.  Also, I think it is controlled with a
bunch of others on a common control.

  The temperature theory sounds good, and I had even considered
something of that nature (but I had not come up with as good a cause as
temperature).  The only problem is I don't think I have ever seen the
light come on.  I just took it as another one of those things like what
happens to pairs of socks in the dryer -- they seem to not come back as
pairs.

	Street lamps seem to go out on me about once a week(I drive short
distances at night). They seem to go out right as the hood of my car
goes under the light.

I had always thought that the missing socks from the dryer transmutate
themselves into excess hangers in your closet.

No, missing socks don't transmute into excess hangers!  I'd like to
know what hangers transmute into, though!

Hangers grow up and become extra bicycles, which during mating season
disappear on their own.

PS  This is NOT my line!  Years ago, I read a story in which a character
makes these observations - I believe his progression was paper cliffs for
the babies, hangers for the teens, adult bicycles.  The discoverer - who
no one believes, of course - is later found dead, chocked, with a wire
coat hanger around his throat.

Oh, is that a strange typo a couple of lines back - "paper CLIFFS"; "F"
and "P" aren't even related on the keyboard!  I meant "paper CLIPS", of
course.

Anyone recognize the story, BTW?  I've always wondered where it was
from.

I saw a streetlight that was on during the day, probably as a punishment
for leaving its post the night before to go party with other lights which
had gone off duty.

Anyone who has studied Hebrew will recognize the transformation of
"clips" into "cliffs".

Perhaps its the same reason that new potholes always materialize out of nowhere
when you're driving over known ground.

debenedi (04/13/83)

How about this:  It's just that people's eyes are  more sensitive  to
streetlights going out than going on.  This explains why people
see them go out but not on.  Also, considering the amount of street lights,
it could be just statistics and No Mystery.
You know, it's like the power of suggestion.  You tell someone that
"their lifestyle" is going to cause they hair to fall out and they'll
believe you.  Why?  Because hair's always falling out, you just don't
pay attention to it  AND  it's "easier" to see hair falling out than it is
to realize that it's growing back.
For example:  You'll be surprised at the number of cars with just one
    headlight.  Just start looking and they'll pop up everywhere.

I, too, read the story, but it would take me some weeks to sort through my
books to find it.  The story involved a bicycle shop that was run by
two men - a small serious guy and a womanizer.  The serious guy was
building the ultimate bicycle and noticed that his other damaged bikes
regenerated when damaged.  This led him to the paper clips/hangers/bicycles
theory.  I won't spoil the end because I think I can find the story.  I
will post it (or its title) to net.books.
