Daylight running lamps
Normal cars have sidelights then dip and main, some (mainly swedish) cars run with "daylight running lamps" which are just dip on in place
of sidelights.
Im aware this is illegal in France, but for UK use, is there anything which requires you to maintain your sidelights provided that when your headlight
switch is in the sidelight position your dip beam bulbs are on?
Hope that made sense 
cheers!

all cars from next year have to have them, like audi and some mercs already do. don't see the point myself...
they have to do stupid stuff like turn off when the indicators are on. not sure about when headlights are on though.

Do you have a reference, that sounds bonkers - and I can't remember seeing one of the Christmas light strip Audi's doing that.
Here's some info from the EU about the requirements (not read it myself yet).

i read it somewhere, but can't remember where. was watching an audi indicating the other day, it was going right, and the right hand leds only
went off, leaving the left hand ones on. i'd seen another one doing it a few months back, thought it was broken already til it went round the
corner and they came back on

yes, but thats permanent sidelights. Im talking about running on dip instead of sidelights by simply not having sidelights....
Is there a requirement for a separate circuit and bulbs or just to have working marker lights with the switch in the sidelight position? (I know its
an mot fail if the standard system just has blown bulbs or whatever)

I've got them on my new Audi (S6) - they are very good for being seen but because they are quite low on the S6, other cars sometimes think
they're fog lamps so I get flashed occasionally! Audi put 5 LEDs on each side of the S6 because it has the V10 – nice touch :-)

To answer the OP - you must have separate position lamps.
But note that DRL are a very specific type of lamp with special requirements - they are not equivalent to just driving around with dipped beam on, and
they are equally quite different from normal position lamps.

thats right - next year they are legal requirement for all new cars coming into the uk to be fitted with daytime running lights (DTRL). the ones we
make now work independantly of the dip circuit.. so on the switch you have
off - this is when the DTRL is on (with ign on)
side - DTRL switches off going to side lights
dip - well its just the head light dip
main - same as
the DTRL are just the dip lights not seperate bulbs just made to operate at a different on position
think thats right from memory - not at work..

Actually, DRLs are a different type of lamp, with different light output and angle of visibility requirements to both position lamps and dipped-beam
headlamps.

i don't see the point in them.
if you can't see something from 500kg to 3.5 tons coming at you, what difference is a few extra lights going to make?

Pre roughly 1930 some cars were wired so that the side lights went off when the headlamps were switched on, in those days they could also get away
with one tail lamp combined with the number plate light and no stop lights. Indicators were still two decades away and even pathetic trafficators
were not yet invented.
In the 1970s some nothern european countries required the front and rear position lights to come on with the ignition and the front lamps to be fitted
with 10watt bulbs rather than 5watt.
The UK tried to get the very sensible "Dim Dip" system standardised where when both the side lights and ignition are switched on the head
lamps illuminate but this was blocked as a euro standard by the French.
However very shortly we will all be buying cars fitted with LED DRLs . DRLs must illuminated when the engine is started and go off when the head lamps
are switched on.

If you cant see a tonne of car driving at you, what hope in hell do cyclists and motorcyclists have? I'm with you on how stupid these sound..

This is why:
Since only about 50% of all reported accidents in the EU occur when DRL-
effects apply, savings must be factored accordingly. Full application of
DRL across all EU countries would, therefore, yield the annual prevention
of :
-5,500 fatalities;
-155,000 registered injured persons;
-740,000 registered accidents;
-1.9 million accidents involving insurance claims.

i totally understand that, and yes it may reduce accidents, but its a bit like saying that all road accidents involve cars running on petrol or
diesel, so if all cars ran on electricity, then there'd be no accidents. which there will.
DRLs may reduce things a bit for the first 5 years or so, but people will get lazy on other things instead

Even if the effect only lasts 5 years, that's 27,500 lives saved and 620.000 less people injured. What if just one of those would have been you
or a loved one? As there are no proven negative side effects from DTRL's (according to the SWOV, who should know what they are on about as they
are the dutch experts on road safety) I think it's a no-brainer, really.

I've not looked at the scientific reports but I can vouch for the fact that I get noticed on the road a lot more in the new car which has these
lights.

i just think that once every car has them, the ones to watch out for won't stand out any more. if you can't see a whole car coming at you,
what difference will a couple of LEDs make?
yes, lsdweb you may stand out, but i really think thats because its something different you have. once its standard we'll be back where we are

DRL's...well, I believe the DoT are currently not very happy with Audi (and a few others) as their "rope" lights apparently
don't meet the UK regs. They're also not happy with the rear light arrangement (I nearly crashed into a new Passat last week as his
red/amber flashing indicator wasn't exactly visible).
I've recently got a VW Scirocco (it's a 10 plate) and i don't know why they fitted a lights switch - doesn't matter where you
put the dial, they're always on!
Long live RWD...
