All the latest road hazard features and best practices when driving will not protect you from inattentive or distracted drivers. But that is exactly what the PulsePro is designed to do. By pulsating or flashing the taillights on your truck, the drivers in the vehicles following behind the trailer will react faster and brake faster, even when they’re distracted. The flashing taillights will also help make your truck more visible at night or in severe weather conditions.
