Why do virtually all manufacturers use black instrument dials which can be almost unreadable while driving in poor light. Ok, you can put the lights on to illuminate the dials, but it would be much better if they used white dials with black numerals and pointers. And no, I'm not partially sighted.

Safety measure - if it's too dark to read the instruments then you should have your lights on.

It seems to me more like an ANTI safety measure: I've lost count of the number of new cars with instrument lights permanently on; result - drivers blithely tootling along in poor light without switching lights on as the panel lights give a false glow of security. Citroën started this with the CX IIRC and now almost every manufacturer has gone down the same road.

I much prefer the lit speedos. I always struggled to read the km/h markings on previous cars (usually orange on a black background).

Fashion. Old cars always had a nice creamy/off-white face with black or dark brown needle, tapered with a point on the end like a clock hand. Black is supposed to look modern and high-tec and computerised and therefore better.

Retro-look cars sometimes have old-style dials.

HI.

years ago I used to own a ford escort 1.8si, the model came as standard with white dials as you can imagine it was great during the daylight but at night the green glow from the back lit dials would almost light up the whole car...i would often put a duster on dash...not the speedo part just to reduce the glare...(the car didn't have a dash dimmer control)

our old (phase 1), volvo v40 has nice clear dials, but the updated (phase 2) v40 has more numbers written on the dials making them less clear...for example the phase1 speedo went to 140mph...the phase 2 went to 160mph....for crying out loud a "1.8sport" will only reach 160mph off a very high cliff.....so as you can imagine the 0-70 part of the speedo is only half the dial.....hmmmmm

My MK6 Golf has quite sophisticated dials in that they are permanently illuminated and their light intensity varies with the ambient light available and so when it's bright sun they are also very bright and hence easily read and when dull they dim accordingly.

I prefer digital displays for legibility reasons: I can't read anything easily - 30 mph signs seem a blur but digital displays are great .

Can't think of anything worse than large digital figures rising and falling all the time!

Agreed. A digital readout is fine when displaying the magnitude of a constant or near-constant value such as fuel level or engine temperature. With a continuously, perhaps rapidly, changing number on a screen representing revs or road speed for example it is difficult to judge the rate of change of the value, whereas the sweep speed of a needle in perfect for this.

Why do virtually all manufacturers use black instrument dials ......

because they are more ergonomic. Look at a black/dark object and your pupils dilate to maximise light input and info the brain. Use a white background and your pupils contract, effectively making it harder to see.

Check out aircraft cockpits - most instruments have black backgrounds.Aircraft manufacturers have spent milloions on researching this topic.

Head-up displays are a relatively recent development enabled by advances in technology.But ask yourself this - would you want all the visual information you receive a a driver, given in a head-up fashion? Probably not. Most types of information fall into two main categories:- Caught and Sought.

Caught is for the very important stuff you get your system/car to 'throw at you' e.g. head-up displays which are difficult to avoid so the info is delivered.

Sought is the stuff you use less frequently and go looking for, essentially secondary info oil pressure, engine tempertature etc. That's where black backgrounds, white pointers on analogue displays give a quick and fairly rough indicator of value. You are not worried about exact engine coolant temperature is it 89 deg or 91? it doesn't matter too much. What's more important is whether the engine is still cold or is it overheating. i.e. which end of the dial is the pointer.

Sorry for banging on car ergonomics are a bit of a hobby horse.

So madf, 30 mph signs are a blur?

Go and get your eyes tested and please stay off the road until you get corrective lenses.

30 mph signs a blur? I wish there was more "30 blur" ! How many times do we get caught - almost - at the start of a 30 zone where there is just one sign (which you may not spot because of a plethora of other signs, eyes looking out for young pedestrians, and a host of other parts of the scenery) and then no more signs after that "because it's got street lights, see, so you don't need them..."

Returning to instrument dials - what do BRers think of my idea of colour-coded speedometers - some kind of back lighting changing to yellow at 35, orange at 65 , red at 75, whatever... it occurs to me that a flash of colour just outside the immediate line of vision, clearly visible but not distracting, would serve as a much more useful speed reminder than constantly having to glance down. Intensity of the lighting and speed increments could be user-set as required.

It was my question which started off this thread. And I forgot to say
at that time "Why do all main instrument pointers have to be red??? They can be very hard to read against a black background.
Why not white, or yellow? When I can afford a new motor the first requirement will be a white speedo pointer.........don't laugh.

At night - you simply see the needle and calibrations - seeing a great white static disk as well is unhelpful at best and distracting at worst.

Serious question, are you sure your colour vision is normal? Most people find red on black to be a good contrrast - think butterflies and moths.

Citroen C5s have both anologue and digital displays for the speed and night or day can be read without any problem. Come to think about my w212 has exactly the same.

Aircraft manufacturers have actually spent millions on replacing instruments with screens AKA the 'glass cockpit'.

I think you will find that modern glass coskpits are in fact digital representations of analogue instruments.

The speed and altitude are of a rolling "ticker tape" disign and engine instruments look like standard analogue guages.

As has been said elsewhere, this is becuase it is easier to spot a developing situation by spotting changes in dials and also the rate at which they change, much easier than looking at just numbers.

The instrument panel should be a 10" LCD that can be configured to any display the driver wants.Obviously the display would show the engine management exception codes too.

Given that car manufacturers are typically at least 5 years behind the rest of consumer electronics ( they are still fitting CD players) we'll have to put up with clockwork dials for a while yet.

Because they put form over function and have forgotten that the dials are there to inform not just to look pretty in the showroom or to show off the latest design fad.

I prefer analogue over digital because most digital instruments are too garish and ape on-line games. get into the cockpit of a modern aircraft and the instruments are at least part digitial and, yet, it's not lit up like some £25 game.

There are some pretty useless ideas out there too. The unlamented Skoda had a neat trick when the auto lights were on, in some conditions the dials would go dark but the needles would be partly illuminated - totally and utterly useless as well as dangerous. "Yes, they do that, don't use the auto lights function if you don't like it" was the reaction from three Skoda dealers and Skoda themselves.

In the past few months I've driven a VW Touran and a Seat Altea and in both cars, one of the clever dashboard options was to project a large digital speed readout in the centre of one of the dials (other options being mpg, fuel range, etc.) I found it very useful and was glad to have the choice - some drivers prefer analogue, others prefer digital; there's no one right answer! Also, getting used to a new car, in this case a hired one, means that memorising the position of the needle in peripheral vision isn't automatic(in my own car the 12 o'clock position equates to the maximum speed limit and I was used to it after four years), so a great big number display was bang on. One further bonus is that a precise digital display (together with cruise control) means less likelihood of being caught by the cash camera trap!
