Warning light labels?
Is it an SVA requirement to label your warning lights? My dash may have as many as 7 lights on it, will they just trust me to remember what they all
mean?

You will definitely have to have the brake warning symbol on one. I dont think the rest matter but stand to be corrected
Gordon
I'm sure I've got one, just don't know where I've put it

i think all the warning lights you legal have to have will need labelling - ie the headlight warnings, fog, brake etc. The alternator isnt a
requirement.
labelling must be visable after dark.

The only light specifically mentioned in the SVA manual is the brake fluid warning light, and that has to be marked correctly with the brake symbol).
Oh yes... it also mentions the rear fog warning light, but only says that it has to be easily visible from the driving position (nothing about
labelling).
Any other lights are your own problem!

The brake warning symbol, is that the "!" exclamation symbol that usually appears on the handbrake warning light or something
different?
If it is the same, is it necessary to have the handbrake light?
Whats the deal with the low brake fluid light test switch? Can you use the press switch on top of the fluid reservoir cap or do you have to have an
illuminated switch on ther dash?
Appreciate any help on theses points guys.
Cheers,
Dave.

The only required brake-related light is the brake warning one, which has the symbol you describe (it actually represents brake shoes in a drum, with
an exclamation mark in the middle!). The manual says that you must have some means of testing this, reachable by the driver.
Most people (and most real car makers) use a switch on the handbrake lever that operates when the lever is pulled up. This indicates when the
handbrake is on, and tests the light as a useful by-product. There is no requirement to have a handbrake warning light, but it is a very useful (and
easy) way of meeting the light-testing rule.
If you don't want to faff around with a handbrake switch you can use a simple push button on the dash - I don't think it has to be
illuminated, but it may have to be labelled as the test switch (not sure about that one - would have to look it up).
The button on top of the brake fluid reservoir is just a convenient way of testing the wiring from the sensor - it's not a requirement, and
wouldn't meet the 'reachable' part of the rules.

Sorry David,I'm still a little confused here.
You said in an earlier post :
"The only light specifically mentioned in the SVA manual is the brake fluid warning light, and that has to be marked correctly with the brake
symbol). "
This is obviously a different light to the Handbrake warning light, and as such does it have a different symbol?
I already have the handbrake light with the ! symbol wired up to a micro switch attached to the handbrake, so that's ok.
Could you clarify the point for me as I appear to be going through a real thicko period at the moment.
Many thanks
Dave

Umm... I'll try a different description 
You must have one light, which is the brake warning light. This tells you if the brake fluid drops below a set level. You must have a method of
testing this light, which can be a button on the dash. Alternatively, you can use a switch on the handbrake.
In the second method (the preferred one), pulling on the handbrake lights the light. This tells you that the handbrake is on, and that the warning
light is OK.
So, when you're driving along, if the little light comes on then either your handbrake is on or you're running out of brake fluid!
The wiring circuit is simple - one bulb, 2 switches wired in parallel, either of which will light the bulb. One of the switches is on the handbrake,
the other is on the brake fluid reservoir.
Clearer now?

DOH!!
Thanks David , you've managed to penetrate the great void which apparently used to house what few brain cells I ever had.
Cleared it up nicely thanks
All the best
Dave.

at a guess, unlabelled switches and lights may fall foul of the design and construction rules, as a general poor idea. Maybe worth a temporary label
for the lest at least. How hard can it be?

Most lights conform to colour codes. Red ignition, orange oil, blue main beam and green for indicators. I think the hazard switch may need a triangle
marking on it, most have.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Is there anywhere in the SVA manual (or elsewhere) that lists the colour codes, or have you summed them all up above?
Hazard symbol won't be a problem because I'm using the switch on top of the Sierra column which has the symbol on it already

That's just from observation while trawling through scrapyards and years of driving different cars. I understand you can have an audible warning
for indicators instead of lights if you want.

This is a bit worrying to me, I have seperate resevoirs for front and back on my brake system. The master cylinders have now provision for any sort
of sensor to measure depth of fluid on them. Im thinking I could get some caps from a scrappy and screw them on in place of the old fasioned ones I
currently have, anyone done this ?

Jeffers,
I see nothing wrong in your idea, if you can find two caps to match, just consider a couple of points.
1) You need to find caps there the length of the sensor corresponds to the minium mark on your bottles of the light will not show at the correct
time.
2) Make sure you wire the caps in parallel so that the light will show if either sensor reads low.
Regards
Simon

Mangogrooveworkshop,
To be honist now I think about it, no I'm not sure
Depends on the way the sensor works, if it's a make-on-low switch then it would need to be paralell, if it's a brake-on-low switch then it
would need to be serial.
Thinking about it further, brake-on-low makes more sence (and therefore serial) as the light would come on, not just at low fluid, but a break in the
wire too.
Ok, I admit it, should have thought about that one a little more. I have a purchased wiring loom so didnt really have to think about that much.

Anyone know of any sensor type things that can be retro fitted to old style girling master cylinders (as fitted to my car already), i.e. drill a hole
at the min level mark and screw them in then wire them up to dash warning light ? ? ? sure they must be available but its just finding the company
that makes/sells them.
Anyone ? ?

Why don't you fit an in-line pressure failure sensor? This is a fully legit alternative to a fluid level sensor.
Not sure how they're wired up, but I know a few people on this forum have fitted them - perhaps someone can help?

James,
do a search on the forum. I remember a topic in which someone mentioned caps with level sensors which are a direct replacement of your caps. I just
can't remember from which car they were.......
