Dipping Driving Lights

A post in the UHF thread on driving lights got me wondering about what people do when using driving lights behind another vehicle.

I don't mean when you are right behind, but maybe 500 to 1000 mtrs back. I tend to dip mine (have HID's which throw for about 1km) so as not to annoy the vehicle in front and then drop back out of sight however; when the position is reversed the lights don't bother me as I just dip the mirror.

I would prefer they have good vision rather than being worried by a little glare. I travel every Thursday from Melbourne to Mansfield at about midnight and driving lights are essential.

How do others deal with this? Does anyone else dip the mirror and carry on? Interested to see if I am dipping my lights unnecessarily lol!

I think by dipping your lights you are showing consideration for other drivers, quite a rarity these days.
Some people that wear glasses, or have other vision problems have a lot of issues with tolerating glare, particularly at night.

So, well done!

Always try and do the right thing. Big believer in karma. But if you are far enough back is it a real isse for the car in front when they can just dip the rear view mirror?

You are only far enough back if you don't light up the rear of the vehicle in front.
If you are following a vehicle why do you need HID lights on anyway? You would only need to see what is between you & the vehicle in front.

True, but if i am 500 mtrs back there is a lot of unseen road between me and the car in front. Have hit plenty of wombats and possums on my Thursday night drives and one night almost cleaned myself up on a tree across the road out of Yea. Without the lights i would have hit it for sure. I would never consider using the lights if it lit up the rear of a vehicle but even if way back it would still be noticeable in their rear view mirror.

What I do, is have a set of Polaroid Sunnies, on my dash, and do not so ceortous people who do not dip their headlights.

Works a treat.

Mind you since I brought the HID light kit, they soon drop their lights if I flick my lights up.

I actually put on the sunnies as quick as a flash, if oncoming traffic does not drop their lights.

Moggs, I tend to dip mine pretty much as soon as I see the tail lights of the other vehicle,you may be able to dip your mirror but what about trucks or cars towing vans and relying on there side mirrors. As an ex truck driver I had many cars drive up behind me on high beam and many who thought because I towed fridgevans that it wouldn't bother me. It does.

As full beams behind me do bother me, even if some way back, i dip mine if the lights catch the car in front, and this again can be some distance. If he goes around the corner and the road ahead in in darkness, they go up again until i see the car in front.

People who drive with spotlights on do not seem to realise than the glare stays for a second or so after they are turned off when lights are dipped. This causes me problems with seeing the road properly after being dazzled.

Agree on the being dazzled bit. Plenty of oncoming vehicles are slow to dip and many don't dip at all. How do you let a car behind know if their lights are bothering you? Flash brakes?

In my case, if that doesn't work flashing the 2x150w rear facing worklights on the cabrail certainly does.

Moggs, I flash spotties, on and off, and and brake lights as well when someone is either sitting behind or coming up behind me with HBeam or spotties on. Have on occasion switched my lights totally off and on several times to give the driver behind a very subtle hint, although it's a bit dangerous. If that doesn't work, I slow right down so that he/she will pass me, then after they have passed and safely pulled back into the correct lane, I hit them with full high beam but only for a second or so, then go back to LBeam. This generally has the desired effect as the car that has just you overtaken switches down and up to acknowlege, or apologise to you. More often than not, these drivers are overtired, and forget to switch their lights down. Some have very poor night vision, and need the extra light to see by and don't care about you, so definitely should not be on the road at night. Of course there are the other kind of driving lights on the newer/later model cars, which are not really classified as spotlights, although they should be. These driving lights, while situated lower on the vehicle should be hooked up to High Beam as is the law for Spotlights. Quite a few of them are 100watts or more, (as much as spotlights). Drivers use them in well lit city roads, as well as suburban streets when there is absolutely no need for them. They are dangerous in wet weather as the glare from them reflects from the wet road surface making it very hard to concentrate on safe driving. One or two cars coming toward you at night in the rain with these lights is not altogether too bad, but when you have 10-12 cars coming towards you with low beam, PLUS these lights, it can be a nightmare. You effectively have somewhere in the order of 3,500 watts of lighting glaring in your eyes, not counting the refractions from the wet road surface and rain. If this is not a good enough reason to hook them up to high beam, then I don't know what is. Drivers with these lights, please think of others and turn them off in the high traffic areas at night.

Hi Moggs
I have always dipped my spotties and high beams as soon as I see the rear of another car, or oncoming lights.

However if I am going into Halls Creek on a Friday or Saturday night, and I know that people are coming out drunk (and they regularly do), I will not hestitate to cause them to pull over by keeping my spotties on.

It is easy to see them driving super slow and weaving all over the road, which tells me they have more than a skinful. I have caused many to pull over, then I give them a piece of my mind, and sometimes stay until they start snoring. I don't want the fools killing themselves or someone else.

I frequently find on the way to Kununurra that I have to give people a flick with my spotties to tell them to dip their lights. I have a work light on the rear, and can give people behind a "request" to dip their lights.

Cheers

That's a good question.

What about High beam.

Should I drop them well back, or wait until one or two hundred metres behind?

Sometimes on a long straight stretch it can be a long time in semi-darkness if dropped early.

If the light field is reaching the vehicle in front, I dip mine. If way in the distance on a straight road and visible light is not reaching them, i reason full beam should be OK.

The ones that P me off are those that run around in the daytime with lights on full. Can they see better ???????

The ones that drive around with the w...........r lights or fog lights on

It is now illegal to have these on except in rain or foggy conditions.

Personally I think they should not be on cars at all as the type of bulbs they put in are not suitable for fog as they are white and not focused at all and just shine back at you.

Time Aussie aligned with the NZ rules on headlights.

Dip only allowed where there are streetlights and if you can see taillights in front of you and as soon as you see oncoming headlights.

I realise on a long straight road this would need some uncommon common sense.

It is also illegal in most states to use roof mounted Driving lights when ON ROAD

There are actually guide lines as to how high they may be mounted on the front of vehicles and from what I have seen the huge searchlights mounted on top of bullbars and higher than the bonnet would contravene these.

Reason is that they intrude into the drivers vision.

If you are not allowed an aerial wider than 75mm how can you mount a 300mm spotlight legally above the bonnet line.

Anything that obscures your vision is illegal.

Doing that or hanging good???? luck charms can obscure a pedestrian and cause your luck to turn instantly bad.

Crystals that flsh in your eyes are especially bad

Any body who does that, and yes Ive seen them, is an idiot.

Below the bonnet line is fine and I dont actually look at my GPS.
I listen to what it says and follow that.

I used a Nokia phone for a while as a GPS and the map wasnt big enough to read but the spoken instructions were fine.

hmmmm .... bonnet lines and restricted vision.

Back in the day .......... ... people that only looked at the little bit of road just in front of the bumper ...... were regarded as bad drivers/idiots.

Surely the same still holds true for drivers today ..... not looking far enough in front to see an obstacle ????

Lets face it .... If a driver takes no action and hits something that darted in front of the vehicle ... from the roadside ....

.........Then the driver was obviously fixated on a point in front and not using their peripheral vision to see the threat from the side.

Driving lights mounted above a bonnet line have no effect in that case. neither do they have an effect worthy of legislation for moving vehicles either .....

.......... because the tiny little bit of road obscured by the lights ... Was visible only seconds before.

Hi Grahm H

You may be correct about roof mounted lights in mopst states, of that I am not sure.

I do not use my roof mounted lights on bitumen, I do not use them often, but on the Tanami or CSR when we go out to locate a broken down vehicle, we use them, and they are quite legal.

Of course we have magnets for the car doors "Lead Search Vehicle", but only really use those during the day if we must.

Just thought I would point thaty out.

Rear view mirror in Pajero dims automatically if hit by bright light. It's all a matter of courtesy if you treat other drivers how you would like to be treated then you are halfway there. If a courtesy is extended to you & you pass the vehicle in front how many drivers acknowledge the courtesy extended by the other driver by "One flash left & one flash right" on the indicators when passing manourve is completed? Most drivers would not have an idea what the hell you are doing. Learning to drive should be part of the school curriculum right up to getting Learners & P plates IMHO

Maths, science, English or history? Maybe they should include it as part of sport.

A large part of driving is attitude, and by the time kids go for their licence they've had 17 years of learning how the roads and other drivers should be treated.

I agree. I do not act on OK to pass flash unless I am very confident that the road ahead is clear. I suppose we are getting off topic some what, my only suggestion about indicator useage was after passing another vehicle & to acknowledge a kind gesture from that driver a "one flash left & one flash right" was a signal to say thanks for the courtesy extended to the other driver. I wouldn't believe in anyway that it is illegal although it was taught as part of our road craft education when I was taught to drive by Victorian Ambulance service. Just noticed prior to posting this, that Police situated on a roadway were intercepting vehicles for head light flashing!!!! Checking vehicles for roadworthiness. Seems motorists were flashing to warn others of a speed trap!! I spoke to my neighbour who stated she was stopped by a Police officer & her car looked at for roadworthiness. She was asked why was she flashing her lights on & off H/beam she said she wasn't (told me she lied) Police officer stated well there must be something wrong with your lights then....checked that all lights were functioning & had a good look over her vehicle too..Made her 10 minutes late to pick up kids!!

From a quick google for road rules.



"51. When use of direction indicator lights permitted

The driver of a vehicle must not operate a direction indicator light except¾

(a) to give a change of direction signal when the driver is required to
give the signal under these Rules; or

(b) as part of the vehicle's hazard warning lights.

Penalty: 3 penalty units. Note Rule 221 deals with the use of hazard warning

I agree with you Lex, although i can't un-train my husband on that one. When i was Europe many years ago, truck drivers regularly used the flick of the right indicator to say it was OK to pass (although onus is of course up to us to be sure it is safe). The equivalent here is the left indicator, and yes, if i see a right indicator start, i pull back thinking he's going to turn. Left makes sense but for some reason, right is the norm here.

FWIW & IMHO .......

For vehicles in front of you:

Dip when tail lights are visible
Dip when front lights are visible.

Trucks ?? ... dip for them when you see the clearance lights ... rather than waiting to see the lower mounted headlights/tail lights.


Applying that uncommon, common sense graham H mentioned .......

On long straight stretches ..... Turn off your driving lights first, and then as the approaching vehicle gets closer ... dip to low beam.

Doing it that way provides a staged, step down in visibility allowing some, eye adjustment time .... instead of being left in the dark after going from superbright lighting to low beam.

Of course all those individuals with super bright hi-beams in addition to driving lights ... have lost that little, driving visibility advantage.

When on low beam .... look for silhouettes/movement in the light provided from an oncoming vehicle ..... Theres, way way too much emphasis placed on the need to "see" which species of roo, is about to get flattened - rather than just avoiding a furry obstacle/threat in front.

Makes for good sales figures for lighting companies tho.

Rear facing lights being flicked on ??? .... as long as the light only illuminates the the area immediately to the rear of the vehicle and doesnt project a beam down the road at the other vehicle .... Id defend the action in court.

If I owned a vehicle with a couple of 100w spots facing backwards .... Id just accept that people would want to smash em off the mounts .....


By the way Graham H ....

Align our light rules with NZ ????

Surely you mean go back to the old way of ..... lo-beam in built up areas with street lighting & defined by the 35/60 mph sign at the outskirts ... LOL

Bit hard to do today with all the fancy, city slicker, freeway lighting which all householders have to foot the bill for.

Like your thinking tho ....

In agree with you Oz Troopy I havent been here long enough to know what used to be.

It does work back home still and if the road is lit why do you need hi beam.

As far as above vision line intrusions Sometimes when turning you can actually follow around so that someone walking across the road can be obscured by things on the windscreen or bonnet.

EG try to read a sign that has a pole in front of it. Sometimes as you go past the pole appears to move to stay in front of what you want to see.

An illusion I know but same with GPS at eye level.

Can block out a Pedestrian quite easily.

I dont make the rules just promoting them .

As far as sillhouettes go I really agree.

Was coming back to Dunedin from Invercargill in a Mini 45 years ago in the dark Could see the white line in first part of a long dip then nothin then the white line.

Thought woops why and slowed down just as a big black cow turned and I could see its eyes. Would have taken the top off the Mini and killed the 4 of us if I hadnt been aware.

The Road Rules VicRoads Roadworthiness requirements cover the operation and use of vehicle lights in Victoria. The Road Rules simply state that a driver must not use, or allow to be used, any light fitted to or in the driver's vehicle to dazzle, or in a way that is likely to dazzle, another road user.

Make sure high-beam lights do not dazzle oncoming traffic or the driver of a vehicle in front of you through the rear vision mirrors. The Road Rules prohibit high-beam headlights from being used if you are less than 200 metres behind a vehicle or less than 200 metres from an oncoming vehicle. However, if the driver is overtaking headlights may be switched to high-beam immediately before overtaking.
Driving lights.....
Must be wired to operate only when the headlights are on high-beam.
Are considered equivalent to high beams, so their use is illegal when driving within 200 metres of another road user.
Must emit a white light.
And there lies the problem with drivng lights in areas with a fair bit of traffic. The better the lights, the earlier you have to dip & the longer the period you drive in relative darkness (while your eyes adjust) until they pass.
Cheers Craig...........
