The Steelmate SBS-1 Blind Spot Detection System uses microwave sensors mounted behind the rear bumper (one on each side) to alert the driver when the vehicle is in the blind spot.

If a vehicle is detected in the driver's blind spot, the corresponding LED warning light in the system (located on the lower side of the windshield pillar) starts to flash, and if the driver intends to change lanes and gives a signal, an audible signal sounds.
The system significantly reduces the possibility of accidents caused by passing or changing lanes.
