BSS2LPB Radar Blind Spot “BAR” is based on microwave radar technology for extended distance and sensitivity. BSS2LPB adds an extra set of eyes and warns the driver if there are any vehicles approaching in either blind spot before and during a lane change maneuver.

Our system uses GPS to initiate operation above 20 MPH eliminating potential fault alerts. Unlike other systems, it requires no drilling or removal of vehicles bumpers. Radar Sensor “BAR” installs top or bottom of tag/license plate and alerts the driver with two compact LED Indicators mounted on the “A” Pillars and a small hideaway speaker.

This Microwave system is more accurate than previous ultrasonic based sensor solutions from other companies.

The kit also includes “Cross Traffic Detection Alert” for backing out of a tight space where you cannot see vehicles coming down isle before it’s too late.
