M. Could the flashing of the turn signal lights every time the brakes are applied become a visual nuisance, especially where traffic is heavy?
No. The PulsePro is programmed to reset the pulsating light sequence only after 7 seconds have elapsed since the previous application of the brakes. This 7-second delay is designed specifically to ensure that turn signal lights do not constantly flash in stop and go traffic.
N. How quickly do the turn signal lights pulse when the brakes are applied?
The turn signal lights will flash 4 times in one second (4 Hertz) before switching off or resuming flashing if they were already engaged when the brakes were applied.
F. Does the PulsePro affect the functioning of lights on the truck or on the trailer other than the turn signal lights?
No. Whether you’re driving and need to brake or you’re simply backing up, the brake lights, the white reversing lights and any other marker lights on the truck or the trailer will continue to function as they would have normally and will not be affected by the PulsePro. The PulsePro does not impair the truck’s or the trailer’s lighting equipment.
K. Can the PulsePro be mounted on a trailer?
Yes. However, given that trailers outnumber trucks by a factor of at least 3, it is by far more cost efficient to install the PulsePro on your truck. Once the PulsePro is installed on a truck, any trailer connected to it is automatically adapted so its turn signal lights flash when the brakes are applied.
J. Does installing the PulsePro require retrofitting the truck or modifying any OEM equipment?
No. The PulsePro is a plug and play adapter that mounts on a truck’s deck plate. Once secured in place, the PulsePro plugs into the truck’s J560 7-pin connector socket. When hooking a trailer to the truck, the 7-pin electrical connection cable is plugged into the PulsePro. It is recommended that the PulsePro be installed professionally by a certified truck mechanic.
C. Has the PulsePro’s pulsating light technology been proven to reduce the incidence of rear-end collisions when installed on a truck?
There is a broad consensus among researchers and government agencies that brake-activated pulsating light systems can reduce the incidence of rear-end collisions. There is also a case study involving a fleet of trucks that demonstrates unequivocally a reduction in rear-end collisions as a result of using flashing taillights.

B. How does the PulsePro reduce the incidence of rear-end collisions?
Drivers following a trailer whose taillights flash briefly when the brakes are applied respond much more quickly by braking, especially if they have been inattentive or distracted. Pulsed turn signals when reversing a semi-trailer have also been proven to provide greater safety; this practice is recognized by many security organizations. The PulsePro now makes this an automatic safety feature.
A. What is the PulsePro?
The PulsePro is an adapter for tractor-trailers that mitigates the risk of rear-end collisions. It pulsates the turn signal lights on the trailer for one second when the brakes are applied and it also pulsates the turn signals while the tractor-trailer is reversing if the trailer is already equipped with backup lights.
