blindspot monitor buzzer addition

[notaGolfR]

I've been unable to find where I asked about this before so SORRY!

The blindspot light in the side-mirrors are too easily missed by me. I have had the side-mirrors out and know where the wires to the little light go. There's a tiny plug to them.
Would it be as simple as wiring a piezo buzzer in series to the plug then poking it into the car interior, or what please?

Agree they are totally useless as a warning , should be red , i like your idea , would help .

Well I was taught to look briefly in all mirrors about every 30 secs especially when I was bus driving so i just sort of flick my eyes around and if the light is on I notice it.

A buzzer would drive you mad on a multi lane road as it would be on nearly all the time in traffic

Now we have BS monitors we do not have to do the risky "look briefly in all mirrors about every 30 secs " thing.

If psychological buzzer distraction-risk on a multi lane road exceeded risk of having my eyes off the road, I would include a gesture operated buzzer operation bypass system.

As the system uses the radar/anti collision, & we are advised not to mess with it, I am unsure about how to achieve the buzzer feature.

Any driver should know exactly where he is in respect to the surrounding traffic, using a blind spot monitor and relying on it takes away that awareness. I am old fashioned when it comes to mirrors unless I could have the Audi camera system then mirrors definitely become redundant. I was taught to scan all mirrors and the dash board every minute and it has saved a few speeding fines as well so I continue to do it.

Hooray Someone else with common sense Cant see every thing in mirrors and on a two lane road its on half the time anyway so I still use the mirrors regardless. Im sure notaGolfR's long list of cars didnt have this facility and he had to use his mirrors. Old habits die hard and are often still the best

notaGolfR: It's certainly doable- IMO.

However, I think you meant "in parallel", rather than "in series" - the irony is that if you connect the buzzer in series, you will further reduce the lamp illumination because of the internal impedance of the buzzer - IMO

Also, you might want to consider adding a variable resistor (in series) with the buzzer as a volume control - the constant sound might be a tad annoying!!

The other embellishment that you might consider is to feed the buzzer through a simple single-pole relay which is wired-up as an AND-gate with inputs being the blind-spot warning lamp and the the turn-signal repeater LED like this:

In this design, the buzzer only sounds if you have indicated a turn AND there is a car in your blind-spot - much more discriminating and therefore more effective as a warning device - IMO.

Anyhow, please let us know how it works-out, if you proceed

PS: I made-up the schematic diagram below from the wiring diagram for a mk7.5 NAR model Golf. I suspect that RoW mk7s will be fairly similar - hope it helps. You might be able to pick-up the warning lamp signal from one of the "coupling points" in the door

Thanks DV52. I appreciate all your effort. As is my custom, I will certainly let you and the forum know my experience if I proceed.

I was all prepared to have an auto-electrician tap into the wiring to add a couple of LEDs to my dash which would light up if someone was in the blind spot. He no as he thought the "Can bus " might be upset and problems created.


Can anyone confirm if he is correct please, or is there a way to do it without upsetting the Can bus?"

Why dont you just buy the lights that fit in the mirror housings.
