In Reply to: laser jammers, got a question.... posted by peterNJ on February 07, 2000 at 09:32:06:

LASER (not RADAR) can actually be blinded by your high beams. Car & Driver discovered this a couple of years ago when they were testing jammers. Turns out that the only part of the light you really need is Infa-red, so they got some fog-lights and located an IR filter for them. C&D:1, LASER:0.

The LASER detector was blinded by the IR. If these units are powerful enough, they could certainly blind LASER. I'm guessing they go around the license plate? That's the single most reflective surface on your car. C&D also found that removal of the front license plate reduced your detection range by about 1/2. Strippign off chome and using a black, dull car further reduced detection range to a point where it was unlikely that they would get a lock on you (assuming you had the IR lights on the car) before you had a chance to slow down (after your laser detector went off).

The conclusion was that it was a whole lot easier to deal with LASER than with RADAR.

Because of the prevelance of RADAR detectors, however, insurance companies like GEICO are buying LASERs for the cops. Unfortunately, the cops don't really like LASER. It's too big and bulky and needs to be aimed. It's much easier to balance the doughnut and coffee in the car with the "comic book" switch on the RADAR waiting for the next revenue source to wander by. If it's being used in your area, it might be worthwhile to invest in countermeasures, otherwise, even if it works as advertised, it's probably a waste of money.
