Hazard lights blinking under hard braking???

vasillalov · 12-20-2010, 09:05 PM

Hi all,

Just a quick question: is there a way to get the hazard lights blinking under hard braking, just like the euro models?

NiVeDh · 12-20-2010, 09:07 PM

Can be enabled with coding.

cb1111 · 12-20-2010, 09:16 PM

While it can be enabled via third party coding, it is NOT legal in the US and you may have insurance problems if you are involved in an accident.

The 3 series should have variable brake lights though; depending on how hard you apply the brake two additional brake lights illuminate.. so says the brochure anyways!

Yep they are the same lights as the rear fog lights !

Yes you have the panic brake lights - adaptive brake lights. I have driven in Europe for years - I have not had them go on automatically - but when the traffic stops suddenly on the Autostrada it is normal to put them on to warn drivers coming up from behind.

I actually managed to get mine on. It was really slippery and I was going to stop in front of a roundabout, the abs system worked hard and then the hazzard light went on, didn't understand anything when it happend

Why? I remember seeing a car commercial on TV about the car turning the flashers on automatically after getting in a collision. Forget which company it was but it was like....

What if a car could automatically enable the hazards after experiencing a collision or something like that lol

bmw turns them on after a collision. During hard breaking your rear fog lights turn on

I know....I was asking why insurance would be a problem.

I hit the hazards if there is an emergency stop on the freeway just to give one more method of alert to the driver behind me!

fdsasdasdf · 12-20-2010, 11:06 PM

Yeah, usually if traffic is about to come to a halt on the freeway I'll pump my brakes in one-second intervals before stopping to try and alert people that traffic is coming to a stop or I'll hit the hazards. It's odd that it is illegal to have the flashers auto-come on when stopping hard; I thought Audis and Mercedes did that.

If you were in a collision and your hazards turn on, that is not an insurance problem.

cb1111 · 12-21-2010, 03:53 PM

Actually, the progressive brake lights are a violation of FMVSS 108 as well since that requires "steady state" lighting.

A general rear lighting primer can be found here although there is something amiss if you find the entire document "interesting."

http://deepblue.lib.umich.edu/bitstr...MTRI-99-31.pdf

Accordingly, if there is a lighting device on a vehicle that does not meet the requirements, then it could lead to insurance liability issues in the case of an accident.

I can hear the "I didn't know he was slowing down, his lights just got brighter and started blinking - I thought it was an alien come to get me so I had to try and destroy it to save mankind."

Having spent some time in Deutschland and seeing this in practice, I use my hazards often when on the highway and having to come to a hard stop with fast moving traffic behind me. For me, it's instinctive, I just reach up and pop them on real quick to get the driver behind's attention.

so that would be a no i guess....

jaza45 · 12-21-2010, 09:19 PM

Its call BDF Brake Force Display and yes it could be enable thru coding. do a search on youtube for brake force display

FRM / NFRM (Footwell module)

Blinking brake force display is BFD2_XXXXX settings I think.

Code:

BFD2_AKTIV
	nicht_aktiv
BFD2_BFD
	nicht_aktiv
BFD2_BL
	nicht_aktiv
BFD2_BL_M
	blinkend
BFD2_BLINKEN
	5_hz
