Can Someone Test this out???

[ILikeRadarIMO]

I was reading on
that Turning on your high beam Head lights can effectively lower the effective range of lidar.... It says they used a contour, and it usually got pts at 1900 but with high beams on couldn't get a reading until 1100 feet... it says it high beams spew their own infrared beams... Can anyone test out and see if high beams makes it harder for lidar to get a reading??? Possible cool find if so...

Wouldn't matter if this were true....driving with your highbeams is ill advised, flashing a cop with your high beams is more ill advised, and turning them on once you receive a laser alert is too late.

This use to be true in the early days of Lidar but no more. Having your headlamps on will make no difference

Yes it does work, but only if you are using the HID type lights. It work with the low beams as well as the high beams.

During our last Atlanta Area Jammer Test we proved this does work and when combined with a jammer it cut my headlight PT's to nothing.

It works so well in fact that I now run with my headlights on all the time.

I don't know how well it would work without jammers, but when I shoot the Laser Atlanta at night and target headlights of cars with HID lights it throws JA-3 codes and takes quite a while to get PT (3-4 seconds) on cars I am sure do not have jammers.

Roy I beg to differ, as I said regular headlight no help, HID headlights, big help.

Can anyone test this, with HIR (Halogen Infra-Red) bulbs? 9011/9012 (HIR-1/HIR-2, respectively).

Also, incandescent-halogen lighting can still present a problem - cyberblob and serg demonstrated this not too long ago, with a late-model Honda Accord's incandescent-halogen DRLs, causing the Laser Atlanta to throw spurious JA-3 "potential jam" codes, with no viable speed reading.

Cat4, if you guys have some time, I would love to see a test done with cars that has small rounded high beam headlights - NOT H4 TYPE HEADLIGHTS. My preliminary test shows that is decreases range acquisition. My theory is that, small rounded headlight design for high beams are more focused light like a spot light compared to their bigger headlight design.

We tested on my car with an LA, and we didn't notice any difference. The ZR4 still got PT on the passenger HL at around the same 500-600 ft mark with or without my HID lows (also did HID lows and fogs runs). Granted, mine aren't OEM HIDs, nor are they a projector style housing (which I'm assuming yours are?), so that might make a difference.

We could try testing in the daytime, to see if that makes a difference, and also, could try shooting a car (not an SUV like mine) with OEM HIDs, to see if that might make a difference.

Oh yea, forgot to add, I have separate high beams (9006 lows, 9005 highs) with the smaller, round reflector. We could test that as well to see if that makes a difference...

My theory is that Hid lamps use an energy pulsation to ignate
the gaz , contrary to tungsten filamant @ constant 12 volts .

What is bugging is the fact that some say the Hid have an effect ,
some don't find any difference in laser acquisition .

Who said '' find me the right frequency and I will jam anything ? ''

Will someone invent the '' jammerinthebulb'' concept ?

I am tempted to use my stock HIDs during the day now, but I feel that combining that with travelling faster than the rest of traffic will just draw even greater attention to me from beyond where I can see the cop.
