K40 Radar Detectors

K40 radar and laser protection systems are designed for easy operation and trouble free ownership.

Now you can again drive confidently when the K40 Laser DefuserPlus™, the most sophisticated anti-laser technology available, is vigilantly detecting and protecting your vehicle. 

This first of its kind, active system is designed to detect and deactivate the laser light signal transmitted by police laser. When targeted by police laser, the Laser DefuserPlus immediately sends out a return pulse signal at the same frequency. Simultaneously, you are alerted to the targeting by audible and visual warnings. 

Finally...a solution that deactivates the speed measurement ability of the laser gun and gives you precious time to react and safely reduce speed. Installs discreetly and compliments your vehicle's interior. And is completely legal.

The K40 RD850 is total speeding ticket protection! The only portable detector you'll ever need. And only from K40 Electronics. 

Designed from the same technology as our signature Undetectable Remote Systems, the RD850 is a technological marvel in a sleek package that requires no installation. Just mount it on your dash, visor, or windshield, and plug it into your cigarette lighter (can also be connected to your fuse box). Dismounts in seconds too. So it's perfect for second cars or rental cars.
