K40 Laser Defuser
Discreet police laser speeding ticket protection....guaranteed.
Complete defense against police laser speeding tickets.
If you’ve ever seen a police officer parked and outside of his vehicle looking at traffic with what looks like a small movie camera or binoculars, you’ve probably just been targeted by LIDAR (Light Detection and Ranging), also known as laser. Police laser guns are short-range (typically 1000 feet), and pinpoint accurate. If the crosshairs of the laser gun are targeted on your vehicle and you’re speeding, they’ve got you, pull over, game over.
Unlike police radar, there is no advance warning with police laser guns. You’re only defense is a good offense with K40 Laser Defusers™.
K40 Electronics introduced the very first Laser Defuser in 1994 (which started the whole laser defense industry), so we know a thing or two about combatting police laser, including the latest variable pulse rate (VPR) guns used today. We build confidence and reliability into all of our products so that, you can drive without limits, knowing you’re protected.
We’re so confident in the performance and protection you’ll experience with our Laser Defusers, they are covered by our one-year “Ticket-Free Guarantee“.
|Radar System Compatibility – All K40 Laser Defusers integrate with any K40 remote radar system, you receive alerts from a single warning display (LED(s) and a hidden speaker for both police radar and police laser alerts.
Stand-Alone Option – Already in love with your current or portable radar detector? The K40 Laser Defusers can be installed on any vehicle with a stand-alone kit containing an LED and warning buzzer, giving you police laser protection you can’t get from a radar detector alone.
Laser Defuser Optix – Features
Each Laser Defuser Optix transponder contains a powerful Nanostack™ technology pulsed laser diode for high optical laser jamming output power and outstanding reliability.

January 2014 Review. A little history before getting to the fun stuff.
Another generation of the well known Defuser brand has made it to the market. Since 1996, K40 has been developing infrared speed detection inhibiting ‘plate frames.’ The jamming techniques have changed over the years(Brute/white noise to pulse match), but the customer service has…Read more
I don’t know what was up today but I must have been lasered ten times by NJ State Troopers in my 100 mile journey today. Not one of them came after me.

LIDAR stands for “light detection and ranging.” A LIDAR/LASER gun transmits a pulsed rate of light at an object, the object reflects the pulsed light, and the instrument analyzes the speed of the reflection. Through this analysis, the speed and distance of the object can be determined. At typical target ranges of 800-1000 feet, a police laser gun beam measures between 18″ and 36″ in diameter. This narrow, infrared, monochromatic, one milliradian laser emission does not scatter like a police radar signal, so there is no advance warning to police laser use.
Unlike radar, laser guns give no advance warning. If you are targeted while speeding and you do not have a Laser Defuser (jammer), you will receive a speeding ticket. Laser is very short-range. Laser gun ranges vary from approximately 800-2000 feet. An officer cannot be moving/driving while shooting laser, and laser cannot read through glass. Laser can target and acquire a speed on a specific vehicle in a pack of cars. Radar is a radio frequency that leaves the gun and spreads out over a great distance. This is why radar detectors can pick up police radar from distances up to 10 miles away. Officers can drive and obtain radar speed readings on vehicles while they are in motion.
Both Laser Defuser models detect the laser light signal transmitted by a police laser gun and notify drivers with a unique audible and visual alert hidden discreetly inside the vehicle’s interior. Simultaneously, the Laser Defusers transmit a return infrared light beam at the same frequency as police laser so the police laser gun cannot get a speed reading. The main difference between the two models is the Laser Defuser g5 uses 10 LED jamming diodes whereas the Laser Defuser Optix uses a single pulsed laser diode.
Laser guns are capable of measuring a vehicle’s speed in less than one second. By the time a laser detector alarms, it is already too late. Only laser jamming countermeasures like Laser Defusers can provide drivers with the time needed to react and safely reduce their speed to avoid a costly ticket.
Yes. The Laser Defuser systems are designed to detect and deactivate police laser signals only. Therefore, we recommend complementing a Laser Defuser g5 or Laser Defuser Optix system with any K40 Electronics portable/window mount or custom-installed radar detector to create a complete police radar and laser countermeasure solution.
Yes. The Laser Defuser g5 and Laser Defuser Optix have been designed to allow integration with preexisting K40 remote radar detection systems. This integration eliminates installing an extra warning light or speaker to receive alerts from the Laser Defusers.
K40 recommends two Laser Defusers be installed on the front of every vehicle. For optimum placement for your specific vehicle, you should consult with your installing dealer and/or call us at 800-323-5608. The Laser Defuser g5 comes pre-installed in a license plate frame for a factory looking rear laser protection solution. In all mounting locations, front or rear, Laser Defusers should be mounted parallel to the ground (not pointing up, down, or to the side) with a clear, unobstructed view of the road for maximum effectiveness.
Since the Laser Defusers emit an infrared light beam that does not interfere with radio waves or any devices regulated by the Federal Communications Commission (FCC), there are no federal laws banning the use of laser jammers. Some states do restrict the use of laser jammers, so K40 recommends checking your state statutes for specific information.
