I have front parking sensors on my car (E92 M3 Coupe) which can be switched on whilst driving. I wonder if these would have the desired effect if switched on, as the must send out some sort of signal?????Originally posted by cantfind1 View Post+1 for Laser pro park they are very effective and completely legal, and work great as front parking sensors!

They need to be a very specific signal mate.Originally posted by jim76 View PostI have front parking sensors on my car (E92 M3 Coupe) which can be switched on whilst driving. I wonder if these would have the desired effect if switched on, as the must send out some sort of signal?????
Most 'proper' parking sensors don't use laser at all. If they used laser they'd have clear lenses, rather than being painted body colour.

If anyone is interested, here's the post I made on another forum about the installation of mine:
One important thing is to mount the heads level. First however you need to make sure the car is level. My drive has a slight slope on it, so I levelled things up by putting a piece of wood under the rear wheels.

I purchased the dual head system, and the next step is to decide where to mount the heads. On an e46 this is a simple decision.
Either side of the number plate in the top corners of the grill are the perfect positions.
Upon inspection, there wasn't enough depth to mount the heads without hitting the grills. So I needed to cut out small sections of the grill to allow the head through.

I decided by far the simplest way to mount the head was with sticky pads. I went to Focus and bought a pack on No More Nails pads. These can hold over 2kg each, so the heads should be no problem.
I found that two pads on top of each other at the front and one at the rear made the head sit level horizontally.
Making it point straight ahead is difficult to judge due to the curvature of the bumper. I placed a long box in front of the car to give me something straight to judge it against.

The cables pass up easily behind the bumper ready to be routed into the car.
In preperation for pulling the cables through, remove the glovebox from the car. This is just a load of screws.
The fusebox at the top right of the engine bay has a plastic tube which passes through the bulkhead. So I ran the cables into the fusebox (by cutting as small piece of rubber out of the cable entry thingy)
The cables were pulled through by taping them to a small stiff piece of wire I fed through.


From inside the car, this is the mess that you will see.

The white plastic enclosure in the centre of the picture is where I put the LPP control box.
The next step was to connect the power to the control box. This was where I actually had a bit of a hold up. It was incredibly difficult to find a switched live wire. Everything in the glovebox area was a permanent live.
After consulting the internet, I found that the loom under the armrest contains a switched live. It's a white/purple wire. You need to unscrew the armrest/centre console and lift it up slightly. This exposes the loom with the connector. I stripped the wire and soldered a cable on, which I then ran to the control box.
For the earth, just tap into any brown wire.
The final stage is the control loom which has the switches and buzzer. I fabicated a little metal box to fit the switches in, which was designed to fit in the ashtray.
Here's everything subtle and as normal:

And in James Bond style, a quick press of the ashtray and the switches and LED are exposed.

Now it's 'simply' a case of re-fitting the glovebox (I found this a pain) after making sure everthing is securely plugged in.
Turn the ignition on, and you should have some start up beeps, and then a flashing green LED.
And for the final pic, here's the front of the car. I think it's subtle enough that most people wouldn't even notice the sensor heads.

I realise this isn't the greatest write-up in the world, as to be honest I was more worried about getting it fitted than taking pictures.
It might be of some use though, and I should be able to offer advice to anyone else who fits one.

The legality thing is questionable really.Originally posted by Bealo View PostNice write up Paul, thankyou :thumbs:
So these are legal??????
I might have to have a go at fitting one of these when i get back to UK.
Wouldn't mind a hand if your free on day????
I know people have been prosecuted for 'pure' laser jammers, and for garage door openers when they don't actually have a garage.
I've yet to hear about a case where someone with a parking sensor has been charged and then fought it in court.
The fact that the specific laser frequency is free to use, and the item genuinely performs another function suggests to my (non-legal) brain that a decent lawyer would be able to fight it.
If I'm free I can give you a hand mate. Even if I'm not, I can give you my mobile number so you can ring me for advice on any issues you have whilst you're doing it.

Other possiblitiy is to run without a front number plate. This will only protect you from camera vans, but not the cops with a handheld speed gun, since he will read your rear plate as you pass and get his mate on the motorbike to chase you down. The really important bit is to have a brand new plate in the boot of the car so that the day you do get stopped, you can tell them that your Mrs. bought the plate yesterday after she noticed the front plate was missing and you got home so late last night that you didn't get time to fit it.....I'll be fitting it today officer. It may be a year or more until you eventually get stopped.
The camera van men just go through all the photos at the end of the day and then pop them in the post to claim the fine - if they can't read the plate properly (or at all), they just bin them - not worth following it up for a £60 fine.

The best idea I had was to use the old number plate that was on the front of the car (full size), rough it up a little bit on the tarmac and stick some stones to the back of it, then happily run without it and if/when you do get stopped it's a case of 'sorry, it has just fallen off, I managed to retrieve it look, but will get it sorted ASAP'!
