I was just wondering….
I really like the LED speedometers and other LED gauges. Knowing that you
are exactually going 73km/h is great. Is it possible to get LED gauges as
an option on most cars (if you want to pay for it) or it is dependant on
whether the car maker offers it with that particular car/model?
Cheers!

A digital readout isn’t any more accurate than the analog pickup
unit or in the case of your speedometer, your constantly wearing tires
on your rig. In fact, your vehicle may not have the correct diameter
tires to go with your vehicle’s gearing anyway. The only way to know
for sure is to be calibrated somehow, and who goes to that bother anyway?
Just because the tires came stock on the car doesn’t mean that they are
the ones that will be ‘accurately’ reading on your speedometer. Just
pick up a vehicle spec sheet and see how many different tires can come
stock on it. Heck, even the same size in different brands have different
actual diameters.
My vehicle speed is analog (it would be a pretty annoying ride if it
were digital). I like an analog speedometer…

I’m fairly certain he meant LED. I’ve never seen a vehicle yet with an LCD
display, although I’m sure they make them.
LCD’s probably would not work reliably in a hot car, and they don’t display
well during the daylight. The nice thing about LCD is their low power
consumption, but that isn’t normally a problem in a car with it’s huge
batter and alternator.

Actually, some are vacuum fluorescent and some are LCDs. You’re right
in that LCDs don’t emit any light, but they are often backlit so that
they, in effect, make their own ambient light and they can be viewed
at night.

Actually, while most radio and electronic clock displays in cars are either
LED or LCD, most of the "Tokyo by Night" electronic instrument clusters
which were popular in the `80s are vacuum flourescent. The intensity of
such displays easily exceeds most commercially available LED displays, while
the sole advantage of the LED (smaller power consumption) is irrelevent
in a car.
Plus vacuum flourescents can be more cheaply designed and manufactured into
fancy shapes, like the wonderful, pulsing "power curve" tachometer that
was available on the 300ZX of one or two generations ago.

Most of the recent vehicles I have seen with those horrid digital
dashes do indeed have some form of backlit LCD display. Most of
them use a polarizer so that the digits appear transparent and
the surrounding area black, hence the impression that they are
LED’s…and yes, you can take the plastic cover off of some LCD
calculators, turn it around, and get transparent digits on a black
background….I’ve done it.
Anyway, back to the discussion, I find it humorous how my neighbor’s
Ford Aerostar Eddie Bauer Edition has digital guages that are
designed to look like bar-graphs. I mean, why not just put in an
analog guage in the first place? And their fuel guage bar graph
only has about 6 segments on it. Accuracy notwithstanding, they
don’t even have the required precision IMHO.

I really meant digital vs analog. How they accomplish it is no matter to
me. I just like it.

In actuality, the displays are probably VF – vacuum flourescent. Corvettes
look like they could be LCDs, though.
Even that "analog" gauge may be digitally controlled on newer vehicles. If
it registers speed in reverse, a computer somewhere is just counting pulses
and sending the right signal to the gauge.
I agree with the preference for the ol’ needle on my dash, though. It
leaves a little room for fudging when Officer Friendly asks, "You know
how fast you were going?". :)

Yes, but the data input rate is many more times the output resolution,
plus, my guess is that it sends a DC voltage to the speedometer, which
is analog. According to digital theory, if the input rate is X times the
resolution required, then you can accurately reconstruct an analog signal.
I don’t have any problems with digital input/processing devices if that’s
what they are doing. If the speedometer movement is smooth, then it’s
close enough for me.
All my speedometers are the ol’ cable-turning-in-the-sleeve hookup to the
transmission, non-calibrated of course.

It really irks me by the manufacturers that have the "digital" oil pressure
gauges. You have an analog gauge run by a switch (digital on/off). With
the switch closed, it reads mid-stroke. With it open, it reads low. So
the driver thinks they’ve got an analog gauge, but what they have is a
little worse than an idiot light. If your oil pressure gauge doesn’t vary
when you drive (rpm), plus vary when it is hot/cold, then you’ve got one of
these systems!
I was impressed to read that the Isuzu Trooper has both "working" oil
pressure gauge plus and idiot light!

a hint – it’s NOT the Lincoln Town Car or Ford Thunderbird of 1980.
Forget about Datsun or Corvette, it was WAY before that. Think
mid-seventies. One of you car buffs out there should know it, but I’d be
impressed if anybody actually had one of these vehicles. (They’re quite

And your tires are worn to the appropriate diameter, whatever that
diameter is, only the original design engineer knows. How do you know
that your speedo is calibrated accurately?
My digital watch says it’s precisely 7:32:09. The clock on the wall says
it’s 7:29:43. I KNOW that they are BOTH WRONG according to absolute time.

Someone correct me if I’m wrong, but don’t most modern cars digitize the
speed at the sensor and then send it everywhere it needs to go in digital
form? I recall reading a while back that Saturns worked this way, and I
assume it is the reason for GM’s "tap up or down 1 MPH" cruise controls:
because the resolution is limited to 1 MPH increments or decrements. I
believe the digital signal is converted back to analog just for the sake
of the driver. (BTW, I’m slightly biased toward analog myself, but I’ve
got a digital in my new car, and really haven’t been annoyed with it yet.)

The option never really caught on — some designs were hard to read in
daylight, and given the nature of the self-illuminated display, it was
easy to go blundering along at dusk without remembering to turn your
lights on.
There are aftermarket add-on gauges in LED styles, both digital and
analog layouts, available via mail-order outfits like J.C. Whitney. For
some extremely popular cars such as Firebirds/Camaros, there are also
aftermarket manufacturers of bolt-in LED displays that directly replace
the factory analog units, but I have no idea whether those are any good.

As for the trivia question, my guess is the Citroen. But what I’m
thinking of isn’t exactly a digital dash, but one that mechanically
flips number signs like some old clocks.

Uh, the little numbers change more quickly when you accelerate. At some
sampling rate, there will be gaps in displayed numbers. The same process
occurs during deceleration. It doesn’t take long to get used to digital guages
provided they are easy to see – a criteria that also holds for analog guages.
I think that it was easier than switching from a slide rule to a digital
calculator.
>I’m just saying that you cant see accelleration as good on digital

The best (and safest) way to see acceleration is to look out the windshield.
I don’t think driving with one’s eyes glued to an instrument guage is a good
idea. But, I think some drivers do just that.

There are a number of reasons for the increase in "silicon gauges" in
cars:
1. They are cheaper to manufacture than mechanical gauges;
2. They can be more reliable over the long haul than their mechanical
counterparts;
3. Because they look high tech, American buyers will pay more for them
4. Combine reason #1 with reason #3 and one gets more profit for
the industry.
And the pity of it all is that the quality of information reaching the
driver in a way she/he can easily assimilate >>is not<< a criteria in
promoting digital gauges. Several human factors studies have shown
that the assimilation of info from a mechanical, analogue gauge ocurrs
more quickly than the digital counterpart.
