I have been doing some research on defeating or delaying LIDAR/Laser guns. Their use has increased and a good radar detector will not protect you from getting a ticket. Yes, blinder, laser interceptor and similar products are the best protection but I am looking at other tricks & tips to help delay the pick-up of your speed so that if you have a Rdr detector that picks up Laser you have the time to maybe slow down. This thread is mainly for people where laser shifters are illegal or for people that do not want to go with the ultimate protection.

I tried to find videos of how easy or hard it is for a cop to pick up a Cayman due to its curvey lines & low profile front end but no luck. I am sure that the distance will be a lot less that boxy front cars.

The main place they point at is the middle of mass due to its reflectivity & especially due to the front license plate. The second place in case the middle doesn't work is the headlights. Upon observation of the headlights, they are not very reflective compared to many other light assemblies as they are angled and the light itself is convex in shape.

Anyone use the Laser Veil stuff?
Any tips or tricks other than not speeding....lol?

The one thing about laser is that the cop has to see you, it doesn't shoot over hills, etc. so if the cop has to see you, then you should be able to see the cop. Now of course they could wait on an on-ramp for you to pass by and then hit you from behind, but that's a good reason to check all off-ramps as you pass them. If you are going to speed then you need to be more aware of your surroundings and where someone might be hitting you with a laser from. Or just get a B2...

There was a suggestion in another thread recently that HID headlamps (when on) can, in some circumstances, impair the LIDAR. I wouldn't count on it though . . .

I read about that but really don't know if it actually works & I am not going to rely on this until there is more evidence to support it

I read something about using light to fool the laser. I believe what I read indicated the use of HID lights with a dark green lens. The idea was to overpower the laser gun . That was some time ago.

The brake lights on some cars will activate my V1's laser detection.

I hadn't heard of the stuff, but found this Test/Review here: Laser Veil Test.

It sounds like it is marginally effective at reducing the range of acquisition, but I'm not sure I would like it on my headlights from an aesthetic standpoint.

I also did a little research on it and its looks promising and buys you some time before they get your speed reading but I don't like how it looks on the headlights. This is something I might consider before a long road trip and then clean it off after the trip. You can also put it on a front or rear clear plate cover to make it less reflective....the laser veil might be useful for this.

Laser works by bouncing off something that will relect it. The police, who have to either be out of the car or with the window rolled down (can't shoot through glass) and stationary, aim at the front plate. If you don't have one, that helps. The large headlights are a good reflective surface. The smaller the frontal area and darker the color of the vehicle also help reduce the effectiveness of laser. In addition to my '07 Boxster S (guard's red), I have a lowered, black Miata with no front plate and pop-up headlights (in the down position) and turn signals that have been replaced with flat black cold air intakes. Probably as stealth as it gets. It only lowers the effective range. Best protection is to hope they get someone in front of you giving you time to hit the brakes when your detector goes off, be very vigilant about looking for police cars or obeying the speed limit!

One highway trick that I have *ahem* heard of, is to fall in about 1/4 mile or so behind someone going the speed that you would like to go . . . i.e. a rabbit, to flush out the radar/laser trap that might be waiting ahead. As manymotors suggests, a laser detector will usually only save you if the car ahead of you is getting painted.

Anybody have experience with laser diffusing plate covers?

 

[motucayman]

have you considered an Escort laser shifter ZR4 or any other laser jammers such as Blinder?

That was my suggestion. it's not about using HID lights - it's about drowning out the relatively dim laser pulse reflection w/ any lamp w/ enough infrared stectra.

In my original post I described it as 'anecdotal evidence' - and I also referred to an experiment Car & Driver performed: take a laser gun, compare capture distances w/ headlights off and on ... not rocket science and there was a significant reduction in capture distance, lights on. ['so simple even a car magazine can do it...']

technical note: HID spectra are not continuous - it peaks at specific points and there may be less @ the near-infrared end of the spectrum. I will probably put 55w halogen bulbs into my fog lamps, and run those in addition to the headlamps, when I think lidar is possible. halogens throw more I/R.

The only way you'll get 'evidence' which isn't anecdotal is to buy several lidar guns and do the experiments. Anyone?

One point is correct - most speed traps are quite visible. the trick is to match your speed w/ what you can see. If the road is too busy, curvy or whatever -- if you can't comfortably take a very long look -- then you're probably going too fast.

The cop is only of of many possible hazards in the road you may need to slow for. If any of them are a surprise, you were going too fast for the conditions @ the time, or, you weren't looking. That could be a cop 'round the corner, or a disabled car in the road, dead cow, bicyclist ... surprises at speed are not good.

mmmv,

In my post above I believe that the the green filter was used to pass the light which would affect the laser while reducing the intensity to the oncoming traffic.

The older guns would suffer loss of performance with HIDs, the newer guns don't, but the bright lights may affect the officers ability to accurately aim, by blinding him. So I say, it can't hurt but I wouldn't rely too strongly on this for protection.

In my opinion, I would call that 'Worst Protection', not 'Best'. Once again, in my opinion, a dash mounted laser detector is worse than no detector at all because all it does is give you a false sense of security. I've been in many situations where I saw an LEO pointing a laser gun into the lane next to me without a single peep from my detector. If that gun isn't pointed directly at your detector, it's not going to warn you. If it does warn you, and you're speeding, you might as well just pull over and get your papers ready.
