Most cop cars in my area have this on all three brake lights.
It makes it pretty easy to discern a civilian car from an undercover out on the road. But I do like them for the safety aspect. The systems they use are probably much better than the aftermarket 'blink everytime' stuff, in that they just flash once before steady-on.
In 2002, Daimler-Chrysler tested the benefits of a flashing brake light.1
From 2006 to 2010, the Department of Transportation (DOT) studied and published a series of reports on the effectiveness of a flashing third brake light showing that a flashing brake light improved the reaction time of the driver in a trailing vehicle by almost 50%.2 The same DOT studies showed that a distracted driver was 69% more likely to notice the car ahead of them slowing or stopping, if that car was equipped with a flashing third brake light.
In short, study after study demonstrates the effectiveness of the Pulse safer braking technology in helping to prevent rear-end collisions.
Pulse is the only pulsing third brake light that meets regulatory requirements for use in all 50 states. Step on the brake pedal and Pulse goes to work pulsing, rather than flashing, the third brake light. What’s the difference? DOT regulations restrict flashing lights to emergency vehicles.
