The Blind Spot Detection System is designed for use on most vehicles. The system uses four sensor (two front and two rear) to cover all four corners of the vehicle. When the turn signals are activated the Blind Spot Detection System will activate and if there is a vehicle in any of your blind spots the sensors will pick up the vehicle and alert the driver with two LED indicators as well as audible tones from a buzzer inside the vehicle. The Blind Spot Detection system works well for all applications such as driving down city streets or highways parking or making simple turns.
