No , because they are not putting out the right wavelength of light to jam, and even then only a few guns would be affected by a “allways on” source of IR, To confuse the lidar gun you have to be transmitting as close to 905nm( nanometers ) as you can at high enough pulse rate to have the first pulse hit the sensor during its gated period.

The problem with trying to beat radar is that you have to know the radar signature of what your trying to hide and then come up with something that will mask that signature. This is the type of thing that only the military/government has the backing to accomplish.

Well only a few headlights source enough energy in the right bandwidth to have any effect, and only in older guns. Sadly Mythbusters has some science but not due diligence. If they had gotten the right LEDS (890nm to 910nm) and pulsed them at about 2 mhz with a 40 ns wide pulse. The LIDAR gun would have been blind. Again however that would have taken effort on their part to piss off the cops. And they cannot afford to do that. There are many many things you will never see on Mythbusters because they need to play nice with the police.

do illuminated headlights defeat lidar?

I have a simple solution that works, you get some very fine sandpaper and scratch off the reflective paint turn your letters into something else, ie e all of a sudden becomes a b upon camera flash, make sure ur rego sticker is up nice and high on an angle and hard to see as well, also dont forget , dont put stickers on your car like for sale, i know an idiot that took his plates off and drove past a roadside camera car over and over, the idiot left the mobile number on his car and got booked

They ignored the original plywood myth after 15 seconds. I just don’t get this ‘science’ show.

Yes, radar works fine in the wind. And yes, another vehicle can make a difference. The radar unit reports on the fastest thing it sees. It is up to the cop to see determine which driver to hang it on (easy enough to do; who is passing who?)

OTOH – radar can reflect off of large signs and potentially report the speed of – say – an oncoming vehicle, when the cop was following you.

The best “science” is a good radar detector. I use a Valentine; it has paid for itself on at least two occasions.

Escort is the other top end brand; you won’t go wrong with either.

I would like to know under what conditions it is possible to fight a ticket successfully. If it was really windy that day is the radar less accurate? If there is another vehicle in the picture is the reading less likely to be true? We will all get tickets no matter how hard we try to avoid them but how can we make them go away without a conviction? Give us the science to create that ‘reasonable doubt’!

I work in an Aerial Lidar Mapping unit. I can say Lidar has it’s faults. I’d say with Lidar you probablt cant use it in the rain, but I wouldn’t know with radar. I can say that there are some colours that are Lidar invisible, but are they invisible to Radar? Maybe the Mythbusters Guys will want to carry our a few more experiments? I can show some examples. Could also be a commercial venture out of this one…. ;-)

I drive truck for a living,and an old myth that has always been around is that police radar do not work when its raining.is there any truth to it,as i do not want to test the theroy myself!
