Antony, For dark twisy country lanes, you will be very happy with the Xenons. The fogs will only be better when the pea soup is so thick that you need the additionla width of the fogs.

Firstly, my applogies...I didn't know that on the Yeti there is a separate bulb built into the front fog light!! I now do!!

I am not saying do this.....however as an example in pitch black conditions, if you were to turn off your headlights and drive solely with front fog lights on or these DRL on... how much visibility of the road does it give you, that you can actually act upon?......at speeds above 10 mph or so...im guessing minimal if any!! Hence, for those driving at 20 to 70mph the visibility of the road that it offers is not something you can act upon. Hence, what use are they?.......I have no doubt people will put them on and drive at these speeds?

Back to my previous email, unless it's foggy, low cloud or misty, or pehaps if you are mud cruching off road etc.....front Fog lights, DRL's are more of a cosmetic, than a functional addition to the car. :p

The DRLs are essentially cosmetic - although the ones on the Yeti are quite bright. It is not easy to drive with them in the dark and they do turn off when the sidelights (and because of the lock on the switch) and foglights can be turned on. I use the fog lights ON OCCASION as infill lights to the normal head beams.

On the roads round here a speed limit of 20mph is advised only because (in daylight) it gives a reasonable chance of stopping when meeting an oncoming car round a bend. A combined speed of 40-50mph with only 40 or so feet to react and stop in takes some doing. Most of the locals know when to speed and when to hold back but the few incomers that we have round here do struggle to stop at times.

... if you were to turn off your headlights and drive solely with front fog lights on or these DRL on... how much visibility of the road does it give you, that you can actually act upon?.....

DRL = DAY TIME RUNNING LIGHTS - means that they are meant for DAYTIME use.. They are an aid for others to see you not for you to see with them.

You don't use or need them at Night - that's what all the other bright lights are for at the front of the car.

Yes some people leave their fog/full beam on when you approach them - it's annoying. But I did it last night - I just purely forgot I was on full beam, ( the steering wheel covers the indicator which doesn't help), and the guy approaching me was rightly none too impressed.

I would have thought technology would be soon here to fix this scenario soon - since if we can have the car parking itself, surely it can dip the main beam or turn off the fog lights when sensing oncoming traffic.??

Did I read somewhere there are cars that do this already??

On daytime running....I'm just not sure what the advantage is over putting headlights on 1st stage/side lights is. Are the rear lights activated, when the DRL are on?

Activating the function daylight driving lights

– Pull the turn signal light lever towards the steering wheel up to 3 seconds after switching on the ignition and at the same time, slide it to the top and hold it in this position for at least 3 seconds.

When the daylight driving lights are switched on, the side lights and the low beam come on together.

In some countries, the national legal provisions require that the parking lights come on together with the bulbs for daylight driving lights when activating the function daylight

driving lights.

On vehicles which are fitted with bulbs for daylight driving lights in the fog lights, the parking lights do not come on when activating the function daylight driving lights.

When the daylight driving lights are switched on, the illumination of the instrument cluster is switched off, however, it is switched on in the position AUTO when it is dark

and the low beam shines with full brightness (100% of the performance).

On vehicles fitted with an information display*, you can also activate or deactivate in the menu the function daylight driving lights:

- Lights & Vision (Lights & Vision)

Great Post Anthony 1 - Cibie's are certainly a blast from my past. I remember them well!! :yes:

:sun:

Cibie' Super Oscas Fog, Driving and Spot. and Bi Oscar which is a Fog/Driving Lamp combined uses H4 bulb

I used to run 2 Driving up and 2 Fog down so foor lights. Massive light output almost daytime. I am sure that they may have updated the lenses every now and then but they are still available for about £100 aprox plus or minus depending on where you buy. You will remember how big they are. Cibie' have more up to date lamps which are even bigger and have a bigger range of beams to choose from

Apollo. Fog, Wide Angle, Driving and spot

They use H2 bulbs which were supposed to be better running hot and producing a greater light output the H2 is a small filament bulb and it was used to give a very tight control over the beam. Unfortunately H2 Bulbs are a little delicate and the rally boys tended to damage them because of the intense vibrations, They are an attractive lamp having a fibre glass modern housing isntead of the old pudding bowl steel ones of the Oscars and Super Oscars. The Oscars are smaller but some come with very modern lenses so perform very well for their smaller size still a lot bigger than halfords own however.n not quite remember off hand all the permeations that they come in much as above but they also have a dipping version with an H4 Bulb and it gives Drive plus Dipped beam in one lamp and are in fact headlamps H130 or H180 One of the lenses is called Allesee or something similar and was specially designed for Endurance racing Porches.

Cibie do many other lamps also but in my opinion they are all a bit small and showy. Hella do some excellent designs, large lamps are the 2000 which is a bit out of date, the 3000 and the most modern 4000. In different parts of the world they might be called different names. Luminator for instance. many car accessory shops might have some of these but they may only have a limited range of lenses like Fog and Drive. Sporting rally shops should have the whole range which for several of the ranges have Fog, Wide Angle, Drive, Spot. The spot might have other names like pencil or long range. For the majority long range will be usless asit gives an extremely long range pencil beam which on any but the most strait of roads will actually make driving more difficult what happens is as you drive the light only projects ahead so as the road wanders the light highlights things that you do not need to see while not shining on the road. For most the Diving Lamps are best. For us that use very very narrow lanes like Terfyn and I, possibly LlaniGraham also, the Wide Angle might give the very best beam for our uses, giving a very broad flood of light. The Fog lights of all the above are exceptionally good forget the rubbish on ordinary cars these will amaze especially if mounted at a more reasonable height.

If some one wants a two beam type but does not want 4 lamps, two of each, either the Bi Oscar Drive/Fog or the Dipping Oscar Drive/Dip would both be excellent lamps. Their are other manufacturers American and Australian the latter tend to concentrate on spot/pencil beams and some very innovative designs have come about some of which are adjustable and very very huge but light weight. Lightforce are the best known. They can give exceptionally long range but on some of the images of the beams that I have seen, they are not so good when adjusted to a wider beam because they have dark spots and light rings. Some come with clip on lenses that further modify the light. I know nothing really about the US designs except that they are pushed quite hard by the publicity machine Some of these use H4 Bulbs. I can not comment on them as I have never seen them. In the USA their are also some very interesting lamps that use LED bulbs. these tend to be flat panels or similar and have amazing off road potential. I have not looked them up in the last year or two but off road they far exceed HID normal Lamps because of the huge flood of even light that comes from them. I do not know if any applications have been designed for road use. It would be niceif they did but legal issues might come about because they may not have the "E"

Dont see an issue with dedicated DLR's myself.

No real issue with them, really. Keeping daytime use in mind.....I just don't see that they have anything to offer, that turning the side lights on (head lights on 1st stage) hasn't offered for the last 30 years or more. It's like fixing something that isn't broken. Bit of a style gimick really!

I tend to use my headlamps if anything in the daytime. I would like to see a device that limits side lights to just being used while parked so that they are not used while driving. The number of people hat I see in poor light /heavy rain just driving on side lights is amazing. They do nothing at all to aid safety, one hardly sees them any earlier than a car without any lights on at all.
