K40 Laser Defuser

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.

Laser Defusers 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 light beam at the same frequency as the police laser gun so the police cannot get a speed reading.

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 system with any K40 Electronics portable/window mount or custom-installed radar detector to create a complete police radar and laser countermeasure solution.

Yes. K40 Laser Defusers 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 three 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. 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.

We have absolute confidence in the performance of our products, and you should never get a speeding ticket when they are operating and used properly. In the rare event you should receive a speeding ticket in the first 12 months of ownership, we’ll pay any and all fines (excludes attorney fees and/or insurance premium increases as well as tickets issued in school zones, construction zones, and/or when DUI or DWI is involved). No questions asked.
