Follow-on to the two-wheel-specific TPX Motorcycle Radar Detection System, the vibration- and waterproof TPX Motorcycle Laser Jammer System ($549.99) reflects the signal put out by police-issue hand-held laser guns, preventing speed readings. The rider is made aware of the signal via a dash-mounted visual alert. An audio output jack allows integration with most helmet-communication systems. Bonus: free software upgrades. Laser jammers are currently legal for use on motorcycles in 40 of the 50United States.
