A blind-spot warning (BSW) system can reduce both stress and the risk of a crash by helping you keep tabs on vehicles lurking over your shoulder and out of sight. But until recently, the only way to get one was to invest in a new car.
Never ones to miss an opportunity, the ever-vigilant automotive aftermarket has risen to the occasion, and a handful of kits are now available to update almost any vehicle with the technology. And we purchased one to try.
The Goshers Blind Spot Detection system includes a sensor for each side of the rear bumper, a left and right side LED warning display, an audible alarm unit, a controller, and all the necessary wiring to link the whole thing together.
The suggested retail price is $250; we paid $200 from an online retailer. A Premium model with two more sensors for the front is available for $350.
