What is the point of having them fitted, as I cant see any need for them.
Should cars be set to dipped headlights all the time?
Or why not just have a choice of Off or Dipped!

Oft repeated here is the dumb fact that the EU binned the UK's initiative for dim-dip headlamps which was a very clever idea. Far too clever to live.

Genius idea. For those who missed them, they were wired so that you couldn't drive on sidelights - the headlights came on dipped, at half voltage. Not only was the car then easily visible, it avoided the unnecessary dazzle of full headlights in busy, well lit built up areas at night. And no high technology needed.

The Americans, quite rightly, call them parking lamps. That is all they should be used for.

In days of old, when cars had dynamos and not alternators, there was a case for switching down to side-lights in town to conserve the battery. It's an old, and potentially dangerous habit that needs knocking on the head.

Biggest problem is that these days the side-light bulb is enclosed in a huge headlamp glass which diffuses the light to the point where it's virtually useless. Thing is that drivers use side-lights in wet weather when they'd be far safer (and so would everyone else) using dipped headlamps.

I have to say, whilst not angel lamps, the sidelights on the Skoda give a pretty good account of themselves.

Sidelights are still the best for that half light at dusk and dawn and in heavy overcast cloud, especially in urban areas.

The obsessive headlamp fetish causes too much glare for drivers to be able to see other road users beside vehicles, and especially behind a strongly lit car, i refer mainly to people and cycles, often poorly lit.

I have upgraded my 501 wedge sidelight bulbs to W5W.
They are very slightly blue but much brighter and are a much better back up for a failed dip bulb especially as they appear white not yellow.

There is an extra bonus ( if you care about appearance) they now match the dip beams in colour.

No, you have all got it wrong.

Sidelights are there, so the few really cool 'dudes' can drive around, with their side and front fogs stroke 'driving lights' on THINKING they look cool blinding' the rest of us off the roads because there is always one of these driving lights not aligned correctly isn't there?.

So surely, that is why we have sidelights?!

I know that driving with your sidelights on it is a proven fact that it makes your vehicle easier to see during daylights hours and minimises your chances of being involved in a 'didn't see you' scenario accident.

Yep, I always drive with sidelights on and I really don't care who it bugs to death (because I always get flashed at least once a day by a Mr or Mrs Meldrew type) out there!

I am too always one of the first at dusk to turn my headlights on - some people really struggle with that don't they? Being the first to turn their car lights on, like being at a wedding reception, the first to go to the toilet? A conscious 'don't want to be seen as leading or the first' psychological thing?

Stop being a sheep and do your own thing for once Baaaaahhhhhh!

Sidelights as we know them - i.e. useable with engine running - won't exist for much longer, I reckon. Cue the EU-wide plans for daytime running lights circa 2012. Plagues of "Look at me, I'm 4 years early with this one" A5s in my neck of the woods are already beginning to irritate immensely. The system seems to follow the North American rather than Scandinavian system, i.e. only on at the front.
So guess how many of the planks remember to switch "proper" lights on when it gets dark? And, no, the oh-so-clever electronics don't take care of that, either. Just as they don't in fog.
I've always thought the German PARKING light system was superb - flick indicator up or down with engine off and you can leave just two lights on. And the British DIM DIP idea was ahead of its time - it's a much better way to go than this North American idiocy.

In the one car I've owned with front foglights I did over 150,000 miles in all conditions and I found the foglights suited the conditions better than headlights... ONCE. For about 2 minutes. And I think I've been in similar conditions maybe 3 or 4 times in 17 years' driving and over 1 million miles. IMO front foglights are redundant/pointless on 99.9% of the cars they are fitted to.

Using sidelights, on my first car, was the means of getting any car audio. The radio would only operate with sidelights on, so I spent my first few months after passing my test driving on at least sidelights, even in bright sunlight.

The on-off knob was broken and for some reason the ignition-switched feed had been switched with the illumination feed. I swapped it round because I had strange reactions from passengers and flashing from oncoming drivers.

That's rather an old article. The current situation, as far as I can tell, is that new car designs approved after February 2011 for the EU will have to be fitted with DRLs.

This press release appears to be dated today:

ec.europa.eu/enterprise/newsroom/cf/itemlongdetail...0

Individual countries may require non-DRL cars to use dipped-beam instead. The UK was opposed to making this requirement EU-wide, apparently, so that shouldn't happen here.

Note that DRLs are dimmer than dipped beams - the basic brightness requirement for them fits pretty uniformly into the series: sidelights < DRLs < dipped beam < main beam. It won't be acceptable for a car manufacturer to just call its dipped beams DRLs.

Volvo DRLs are the dipped beams.
You have a choice of all off, markers on or markers and dipped headlights with the P2 cars.
I had mine switched off as the dipped headlight bulbs required replacment three times in twenty-one months. I was charged twice by Volvo main dealers as dealer number one could only do half the job (switched off the dipped healights but couldn't manage to do the markers) but still required paying for connecting up to the central server.

While there may well be a case for properly adjusted dipped beams in most circumstances, I do think having sidelights as backup is a good safety feature. I had an instance where on returning to Heathrow very late at night and faced with a long haul up country only to find that a dipped headlight bulb had blown. I felt a lot safer knowing there was at least a sidelight to mark the dimensions of my car to oncoming traffic until I could replace the bulb the following day..

Having said that, this is the one circumstance when I would be tempted to use the front fogs unconventionally despite any legal implications. In other words as short term emergency back up.

I think dimmed dipped beams might be able to meet the DRL spec - not totally sure. But not at full brightness - if that's what Volvos do (and I haven't paid much attention), they wouldn't meet the new DRL requirement. Too bright.

Sidelights are indeed there as a backup - they're not allowed to fail just because a headlight has failed. But I am regularly amazed by seeing cars with both a failed headlight and sidelight on the same side. Idiots.

I recently had a rear indicator bulb fail late one evening far from home. A stop for a replacement bulb at the next petrol station and a 2 minute bulb change resolved the problem, not rocket science. It is so easy to check your brake and rear lights when you are stopped with something reflective behind you.

There has been many replies on how difficult /impossible it is to change bulbs on quite a few different makes of vehicle so it IS closer to rocket science.
Wishful thinking esprcially when a regular requirement like refuelling fails.

I have changed dipped beam bulbs & indicators on my 98 Mondeo and it requires removing the grill etc and the whole headlamp unit.
I do carry a FULL set of individually selected bulbs that I know fit my vehicle.
On line guides for my car are wrong so what chance an off the shelf kit?

Take a look at the cars on the roads today and they're lit up like Christmas trees compared to cars of 20 years ago. I remember the wonderment of finding my Dad's Cortina XL had an illuminated glovebox, and when I saw two (two!!) engine bay lights on a neighbour's Rover P5, my eyes nearly popped out of my head. I was truly in lighting heaven with my Montego's illuminated column stalks, illuminated heater controls, illuminated minor switchgear...
Just a random sample - my contribution to the automotive version of Ambrose Bierce's " Devil's Dictionary":
* puddle lights: to light up the puddle you just stepped in.
* Ground-level front foglights: ditto.
* Orange side marker lights: for cars that think they're lorries. e.g. Volvos.
* "Ambient light" (orange downlighter fitted to Astra G interior mirror): so you can confidently engage fifth gear on a night drive. Not to be confused with...
* HGV cab ambient light. Usually blue, red or orange. Helpful for late night truckers who want to get that Sudoku finished before Newport Pagnell services
* Footwell lights: enable driver to find discarded undergarments of recent travelling companion before embarking on shopping trip with other half; enable front passenger to avoid stepping on sleeping cat, party trifle or forgotten roller skate (all of which are regularly found in car footwells the length and breadth of the country) It is estimated that lighting for rear footwells, 500 times more useful, will not be thought of for at least another 50 years.
* Washer jet lights, usually blue. Give a nanosecond's warning of washer jet about to hit the windscreen. Just in case, erm,... er...

In half light with a car behind with you with dipped headlghts on you are half invisible to oncoming cars. Just put dipped lights on too and stay visible and safe. It won't cost you anything, just do it.

Nsar is right, as back as 20 - 30 years ago the Police were training their drivers that if it's dark enough to warrant sidelights then that means there is reduced visibility, and if there is reduced visibility then you legally need... (drum roll please) .... dipped headlights!! :-)

Also something that I taught to my pupils as an ADI.

I'd completely forgotten the ultimate car light of all time... the Wolseley radiator light.
Minute's silence.
It communicated two undeniable messages to the British public until 1976:
1. Slow down, I might be a police car.
2. While this light shines, Britain still has its own car industry.

Yes, nsar and Blue are correct. Or at least, that is what I was always told.

But last week I began to think that maybe, just maybe, there was something in what gordonbennet says.

I found that in dull, cloudy conditions, driving on trunk roads, there was a variety of practice. Where oncoming vehicles had no lights at all, they were visible, but I felt that it would have been helpful if they were just a little more visible. Where vehicles were on dipped headlights (at least I am assuming that they were dipped headlights), I found the glare was often uncomfortable on my eyes. I felt that the few heretics who were driving with sidelights were the ones who had got it right - IMHO.

Perhaps the received orthodoxy on this one is not as correct as I had always believed.

In my post you will find i was referring mainly to urban situations.
This is the trouble with today's motorists, only the motorist counts, but as responsible drivers we owe a duty of care to all road users, and not running them over comes high on that list of duties.
Many other people around in urban situations especially will not have the benefit of hundreds of unnecessary watts of light power, and with everyone trying to outdo each other in the 'look how powerful my lights are' stakes the poor old cyclist and pedestrian become invisible against this sea of glare.

Its not quite the same but its along similar lines, back in the early eighties i was driving my trusty old truck along the M6 southbound Birmingham elevated section early evening, dark, light rain but good visibility. Almost every car with the new fangled rear fog lights had them on, now being in the sole truck on that night, i could see hundreds of high intensity rear lights ahead, if anyone had braked i probably wouldn't have been able to distinguish the blessed brake lights, it was a truly dreadful drive home.

OK fast forward to the present day, as soon as the sun goes behind a cloud we have the knee jerk reaction 'i must be seen' and on go the lights, quite apart from the growing minority who need them on all the time, its ludicrous and causes constant glare, which diminishes a normal persons vision of things that arn't lit.

Think how difficult it can be sometimes on dark wet nights with a constant flow of traffic the other way on a 2 way road, trying to use oncoming car's lights some distance ahead to create a silhouette to navigate by.
Now modify that into the half light urban situation with pedestrians and other road users trying to shuffle their way home huddled into their invariably dark clothing, not always looking out as they nip across the road.
Its your opinion that i'm wrong and you're entitled, but there are other ways to look at it.

I think headlights should automatically switch off when the car is stationary. When I'm stationary at the head of the queue at traffic lights I find it annoying when the driver of the car on the other side of the traffic lights doesn't have the courtesy to switch off his headlights. At one time it was common practise for drivers to switch off their headlights when in this situation. Nowadays thoughtfulness like this seem to have gone by the board.

there ARE times when sidelights can do, (not for very long though)....i.e. when it has just become twilight or dawn

but...sidelights will NEVER do in fog or heavy rain

Sidelights-what purpose?? - Harleyman
Absolutely, Westpig. When there's a lot of spray around, overtaking with a lorry becomes a lottery, even with the most careful use of heated mirrors. A silver car with sidelights only is virtually invisible till it's almost alongside you, and since they seem to be in a majority, they really are a menace.

I am fully aware that some of you will suggest that I should not overtake in these conditions, but if you're pulling over to avoid a hazard (accident, or a slow-moving abnormal load for example) the same thing applies anyway.

I wonder if it is because some drivers think that, on motorways, nothing's coming the other way so they need not bother so much?
Sidelights-what purpose?? - scouseford
One factor that doesn't appear to have been discussed in this current thread is the cleanliness of headlight/sidelight lenses. After driving 20 miles or so on a busy road in foul weather conditions the lenses can become badly obscured by spray thrown up by vehicles in front. This can have a serious impact on the amount of light that gets through. You don't see too many drivers cleaning their lenses at motorway service areas.

One way of dealing with this problem is to use glass cleaning spray on the lenses on a regular basis. It's surprising how much cleaner your lights are after this treatment - presumably because the s---e slides off a little more easily.
Sidelights-what purpose?? - Bilboman
Cleanliness of headlight/sidelight lenses...
The Swedes sorted that out in the 1970s with the wonderful wash/wipe systems, first used IIRC on the Saab 99 EMS/GLE, which subsequently evolved into power wash systems. These then became toys/"must have" luxury items offered or standard on such varied cars as the Mini Metro and Lada Niva and top-end Fords, Talbots and Renaults. The RR Silver Shadow had ever so gentle brushes, probably ocelot whiskers, but I'm only guessing. (Did wash/wipe systems of the 80s merely distract us from the rusting wheel arches, or somehow contribute to them?)
Incredibly useful in snow, quite useful in rain, probably not much use on the Costa del Sol - which might explain why the ever "obliging" EU overruled domestic Swedish legislation requiring all cars sold in Sweden to have them fitted, so that they're now legal but not compulsory. Now making a comeback with HID/Xenon lighting units.
