Read on post #10 on the following thread http://www.briskoda.net/forums/topic/262499-2nd-fog-light/ that it's hinted that via vcds or whatnot you can make the brake lights flash when you slam the anchors on, as happens in other makes of car.

Anyone done this or know if it's actually possible?

Are you thinking of 'Flashing Hazard Lights' (Orange lights) when you brake hard.

Hopefully your Brake lights stay on constant while braking.

Depends on the year of car, early ones you can set the brake lights to flash, newer ones the hazards come on.

Certainly later cars have the option for flashing brake lights or hazards warning lights I have activated several cars, the only issue is it looks like need the ABS to cut in to test it is working… ideal in snowy conditions.

So either way it can be set so that something can flash, correct? Is that's the case, how do you do it? Mine is obviously pre-fl.

Somewhere on the CECM with VCDS.

Don't have a scan to hand, sorry. It is just a tick box.

That's good enough, at least I know I can definitely do it on my motor. Cheers.

Don't own vcds but my mate does,... what's CECM??

You need VCDS, it’s under 09-Cent.Elec.

what's CECM??

Central Electronic Control Module

Good man.

The latest Vectra's rear flashing brake lights are very effective. I was following one at some distance a few years ago just before he met the end car in a traffic jam and despite his best efforts was unable to stop. It was only the LED high level brake light that flashed, not the normal incandescent bulbs, but it served it's purpose and made me take notice very quickly.

The other week I was following the new Insignia, it's incandescent brake lights flashed under heavy braking, but alternated from left to right, a little like the rear fog lights are set on Police car's - again effective in alerting following road users.

Hopefully your Brake lights stay on constant while braking.

Another 'modern' use of lighting George, how you gonna cope!?

I'm looking forward to hearing your acronym for flashing brake lights!

You have the 2 options

I myself just ticked the hazard lights.

Mine is pre-FL and I have activated hazards, seems to work under heavy braking without ABS cutting in.

Yep, you don't need ABS activation for the hazard lights to cut in.

It should be noted that "Flashing Brakelights" also activates the hazards as soon as you come to a standstill.

Emergency braking activates the flashing brakelights, once the speed drops to 0mph the hazard lights are turned on automatically...

I understand modern brakes and lighting thank you.

I see those Fiats and others driving at 70 through Glasgow in the outside lane and touching brakes and hazards coming on.

Everyone travelling quite safely at a distance and someone covers their brakes.

I also understand hard braking, & how long that lasts and how a bright pair or three lights tell you someone has hit their brakes.

It does not continue to be hard braking tho does it,

The speed gets reduced greatly, or the vehicle might even stop/halt as in the video.

The ABS and snow to test it on was an interesting comment.

Many of us would modulate your braking even if the vehicle has ABS,

no the surface and the braking needs and requirements of steering or stopping but not locking.

and sliding,

no traction is no action and that includes not stopping with brakes slammed on. Even with ABS.

Sometimes those with the bright ideas and brains, modern thinking and understandings need to drive to the conditions and with some degree of safety.

ie,

I love how those that have the lights, cornering fogs etc seem not to see potholes or know when to slow down.

all the gear and no idea comes to mind.

Don't make it personal George, cornering foglights or emergency lighting doesn't make it any easier to avoid road defects on straight roads.

Whilst not illuminating potholes they are quite effective at identifying keyboard warriers, especially ones that really 'don't get it' despite the repeated, polite, restrained and lighthearted efforts of many

Personal !,

i read post #12 and thought, there he goes again making it personal. Spot what you did there?

Keep your lighthearted for your buddies,

maybe with me you were trying to take the pith and be a Keyboard Warrior IMO.

george

It was light hearted, no mallice intended, unlike making light of my unfortunate incident.

All brake lights tell you is someone is braking.

That could be gentle braking or full emergency braking.

The flashing feature (whether that be the hazard lights or the brake lights) afford the car behind an extra split second of warning, which as we all know through the benefits of LED brake lights can make the difference between running into someone and not running into someone.

Many of us would modulate your braking even if the vehicle has ABS,

to slow down.

Really? Why would you try to cadence brake in an ABS equipped car? Surely the ABS system can modulate the braking far more effectively than even the most skilled driver?

Would you just hit the brakes on the M8, even if icy or maybe with some snow cover on it.

Not a great idea to expect the ABS to bring you to a halt on snow or low traction surfaces.

even if you are driving to the conditions but need to do an emergency stop. JMO.

Some of us drive cars and think and try to drive safely.

Trial and hopefully no error can sometimes help in deciding how to drive or use your vehicle.

The Video in the post in the Fabia section is interesting and shows the lights possibly better than the vid of the Octavia.

george

Cadence braking wouldn't work in those scenarios either. Obviously in those conditions you would try to avoid hard braking, or even braking at all, but sometimes circumstances dictate you need to lose speed quickly and in those circumstances ABS will beat cadence braking every time (unless you're on gravel or deep fresh snow).

The link you posted doesn't work :-(

Funnily it can and does work and the usual proof of the pudding is when it has and did.

You stopped safely and no accident occurred.

So i will do it my way and lets hope that you are not behind me if i need to stop and you are doing it your way.

Works now hopefully, just like my braking. touch wood and hopefully no touching cloth.

george

This is true to a degree, but remember ABS only activates when the alternative is the wheels locking.

If you slam on your brakes hard and fast so that ABS activates immediately, your stopping distance will be longer than if you had braked moderately hard initially (to get weight shift onto the front tyres), then progressively brake harder and harder so as to be just on the verge of ABS activation. Using this braking technique on a dry road results in immense retardation.

Edited 20 January, 201313 yr by booke23

The moment of maximum retardation occurs at the point just before the tyres break traction. ABS achieves this point many times more frequently than any driver can achieve with cadence braking. This is also why cars now have emergency brake assist, detecting that you are emegency braking and adding extra pedal force automatically to the point of triggering the ABS.
