Whether you like them or loath them, they are here.

Why are they only fitted on the fronts and not the rears?

I only ask as I see many people driving around especially in low light or dark conditions, with only their DRLs showing. I presume they think they don't need to switch their lights on. I bet they don't even realise they don't have them on the rear.

So for safety, if these lights are compulsory on new cars, then to prevent such forgetfulness or stupidity, any cars with DRLs MUST have automatic headlights fitted as standard. To stop drivers relying on the DRLs only. And fit DRLs on the rear as well.

An assumption that wouldn't have been made if there wasn't a 'safety' feature fitted that further detaches the driver from his environment. The Audi ones look like a council house at Christmas. Vulgar. Ugh!

LMAO! Good one.

I think there's a strong element of "ooh, look at me, cool" thinking with these DRLs too. With some models the LED DRLs go off when you switch on the "proper" headlamps, so people avoid switching their headlamps on. Very safe (;>)

I have noticed even some new cars appear to have these stuck on as an afterthought. The worst so far being the new Clio, which looks like a kit has been bought off ebay and stuck on the gap in the bumper.

Enough indeed. Hopefully we will vote out of Europe and can get rid of them and all the other stupid laws that have been imposed on us

Do you seriously believe that, as nation of 60m offshore of a community 10times larger, we'd avoid their regulation?

Of course not. We'd just have thrown away any influence over the rules.

I'm sure that will work, except where do you think Clios and Audis are actually made?

At least British manufacturers could get rid of them, except there aren't any...

DRLs - RT

DRLs are fitted according to regulations in specific countries, nothing to do with where cars are built.

If the UK left the EC, we could change our legislation if we wished - but I don't think we'll leave the EC - any more than Scotland will leave the Union.

Some DRLs are far too bright (Mercedes/Citroen comes to mind) - I dont know why they cant be made to "adapt" to ambient light - after all its illegal to use halogen bulbs greater than 65W - presumably because they're too bright, so why dont then look at drl brightness?

Another disturbing trend is the the fashion over function trend. The other day I noticed a car (might have been a range rover - might have been an Audi) with the usual fancy strip of drl leds at front, the front indicator consists of DRL strip flashing white to amber/yellow and back to white. Unbelievable! Hardly noticeable unless yhour staring at them.

I have big issues with a lot of (mainly rear) LED lights - overbright point sources (to make up an average illumination) - poor viewing angles - multiplexing that gives distracting effects - and a combined tendency to give my eyes persistent after effects - resulting in temporary reduced vision due to blind spots.

Also I find the colouring of some, particulary yellow, unnatural.

Also the sharp on/off brake/indicator strangely does not convey the same urgency to me as traditional bulbs soft on/off.

Thin strip rear lights are in my opinion also dangerous.....

As for cornering fog lights......

Dangerous fashion trends.....

DRLs - daveyjp
Facelifted Civic has the worst rear indicators I have ever seen, a single bulb in a tiny housing. If you aren't directly behind the car you won't notice them.
DRLs - unthrottled

I thought it was just my bad eyes that was struggling with rear indicators buried in a sea of fairy lights!

The bright strip lEDs are really distracting when they catch your eye in your rear mirror. You become more aware of what is behind you than all the objects in front of you. This can't bode well for safety.

DRLs - LikedDrivingOnce

That's offensive. I think that you should apologise to ordinary, decent council house dwellers for associating them with Audi!

DRLs - Zuave

Agreed....simple as that really!

Especially the point relating to viewing angles of indicators. Some Audi have very thin rear lamps and the indicators are very tricky to see unless at a very shallow angle. Similar issues with (especially VW) circular rear light arrangement.

It wasn't meant to be witty, it was sarcastic. I have no trouble seeing or distinguishing the different elements of car tail lights and my unaided vision is normal, so I would suggest that anyone who does have difficulty must need help.

Quote from www.worldcarfans.com/113032155437/audi-a8-matrix-b...s

NHTSA is not certain LED lighting can improve safety, adding rear-end impacts has increased in many of the models equipped with LED brake lights.

Possible there is a real world problem with LEDs in some rear light clusters??

There are those who've had trouble seeing components of modern lighting arrays and those who have yet to do so. You appear to be in the latter camp.

As somebody else said certain Audi models have indicators that are less conspicuous than they should be. Also, those models where stop/tail are concentric around indicator or v.v.

Take it from this ex-Automotive R&D Engineer that the case for DRLs is compelling. So compelling that even though the EU dithered over their introduction into ECE Regulations, many member states brought in unilateral legislation requiring all motorists to drive with dipped beam on at all times.

One day you might owe your life to their fitment. Your risk of being involve in a fatal acident is considerably reduced by being more visible to others.

Ben makes a good point. However legislators will have taken the view that the fitment of DRLs in no way diminishes the responsibility of the driver to make use of his (or her) dipped beam as appropriate and required by the Highway Code.

I'm in agreement that some DRL systems just look plain stupid. Audi especially. i like the Dame Edna analogy.

No. Cars with DRLs are less likely to be involved in an accident because they get noticed. The tempting but entirely erroneous conclusion drawn from pilot studies is that DRLs reduce the risk of accidents. They don't. They just displace the risk of accidents onto other road users which gets lost in the noise of data.

A similar argument could be made that because marked Police cars can get to their destination more quickly than 'ordinary' cars, that we could all get to our destination more quickly if only we dressed our vehicles in Police livery. The chaos that would ensue is self-evident.

The problem with the fairy lights mantra is that drivers stop looking for objects and start looking for lights instead. This leaves vulnerable road users even more vulnerable.

Any student of optics will tell you that when you place a brightly illuminated object next to a dim one, the dim one becomes less visible than it would otherwise be.

On my way to work this morning a car was coming towards me with DRLs on. As it went under a fairly wide, dark railway bridge I'm sure the DRLs went off and the headlights came on. It was quite confusing for a moment - did I imagine this or would automatic headlights coming on haveturned off the DRLS. It was a Prius.

Perfectly possible, see my post further up. On many (most?) models, the LED DRLs go out when "normal" headlamps go on. Including ones with auto headlamps.

DRLs - gordonbennet

Agree with some of the postings further up re dimly lit objects fading into invisibility.

In this battle for light supremacy...my dad could beat your dad up...things are getting out of hand, its all very well giving each new model even more ludicrous (and rather camp but each to their own) fairy lights to make them noticed, but in all this light display the poor old pedestrian and cyclist gradually become invisible, let alone all inanimate objects unless lit with fairy lights or covered in reflective coatings get increasingly hard to see too.

The other effect of this rush to fit LED's on everything is the flicker effect.

I'm mainly thinking of some of the fantastically overbright brake lights now fitted to many cars, over the top or what, so bright in some cases that nothing else can be seen when that massive glare hits you...unfortunately due to the flicker and blinding effect the following driver has no idea of the rate of deceleration of the car in front, sensibility required in this field.

It doesn't help when all the lights are crammed in together in one light unit, often chrome lined inside clear glass to give that Lexus light effect, once the sun hits all that chrome inside clear plastic then its a dickens of a job to see any lights at all...this applies especially to indicators all but invisible beside overbright headlights and brake lights.

As for the specsavers jibe, its those who can't see vehicles unless they're lit up like a council house at Christmas that need the optician most.

DRLs - Zuave

Brum - Thanks, I am eternally grateful for your leaping up to support me :-)

Ordovices - I have used independant opticians for many years as I prefer to keep my custom local, but I do appreciate your concern for my welfare and those around me. However, be safe in the knowledge that, although I may not be able to see the indicators at the rear of some types of vehicle, I am always aware of any shift in direction of aforementioned vehicles and, therefore, I am able to take corrective action without further ado. Furthermore please allow me to expand upon my initial comment by stating the following:

....The problem is exaggerated when I am overseas on business (as I am currently) and I am using my UK car. I, being to the RHS of the vehicle and, for example, having a car indicating right to move over from a lane next to me, creates a greater distance between the rear light of that vehicle and I than would be usual were we both in UK and RHD vehicles or both in mailnad Europe with LHD vehicles. It follows that the greater distance caused my being on the RHS of my car, also creates a less acute viewing angle.Ergo the indicators are even less visible.


I trust this may shed a little more light on the subject?

Daytime running lights are a good safety idea and have, rather unexpectedly, also become a styling gimmick. I'm wondering about what will happen in, say, 10 year's time, when most cars will have DRL. Will the few cars that don't have them be at bigger risk of not being seen, or will the law be that if you don't have DRL, you must used dipped headlights in daytime instead?

As an aside, today I was driving along an A road and there was a Scania artic coming the other way. I was cofused by a green light that looked like a traffic light that seemed to be shining from inside the cab. And sure enough, on the back wall of the inside of the cab, there was an illuminated decoration with lots of green LEDs. Whatever happened to 'professionalism' in the road transport industry? !

Back to actual DRLs.

I fear that as mentioned elsewhere, they are really being regarded more as bling. The Audi ones (Clarkson first referred to the fairy lights several years ago IIRC) will appeal to stereo typical (in some peoples' eyes - sorry for the pun) drivers of said cars.

Interesting to see that other cars in the VW range - VW badged ones especially - have conventional 21w tungsten DRL lights. (Not as posh as the LEDs). And even Ford now have those on the facelifted Fiesta, although if you up your model status, they seem to have LEDs.

The ones that are IMHO as annoying as the Audis, are the Range Rover Evoques. How twinkly! Appeal to the targeted owners - not that they are likely to realise that their Posh n Becks mobile has them. And I agree that all DRLs unintenionally cause danger, in that the rear lights do not come on with them. Cast your mind back to the dark/misty mornings of the winter, and how many cars did you see pootling along with their DRLs quite noticeable, but no rear lights to see? I predict a possible increase in rear-end shunts.

My car has DRLs (non LED) and I have decided to turn them off all the time via the computer thingy, and use my intelligence to switch my lights on by using my brain. Novel, eh?!

Example seen yesterday. An Audi SUV, I think a Q5.

DRL's were like a string of fairy lights around the heads. Rather twee to my mind but they did, whether good or bad, what DRL's should.

The rear indicators had the profile of a pencil sandwiched between other parts of the fitting. Useless. Doubtless more so viewed from height, say a lorry cab.

DRLs - Ordovices

By my reckoning if the lorry driver was closer than around 6m (the driver's head could be 1.5m behind the front of the cab giving a bumper to bumper distance of 4.5m ish) then it is possible that they would be outside of the field of view, that's with a guess-timate of the height of the tail lamp and the car being built in accordance with the regulations.

Of course it's a fact that this could be happening at 50mph.

Not all DRLs are set up to be just front lights. They can be configured on some cars to show front and back together, the indication being that the dash lights are out so that you can't see the instruments.

There are some instances where you may not want headlights on in low light conditions, fully automatic systems may not allow this.

My question is where do you stop taking responsibility from the driver for their conduct? Automatic speed limiting, Immobilisers that prevent driving if uninsured, sensors to stop running red lights, compulsory auto gearboxes in eco mode?

I'm sure the technology is out there.

We could always do that in the old days just using the light switch - although I personally subscribe to using properly adjusted dipped headlights (plus taillights) in all visibility conditions less than optimum.
