If your car is a bit older or you were cheap and didn’t spring for parking sensors, that doesn’t mean you can’t add them aftermarket. Sounds good but drilling in to your bumper or running wires isn’t necessarily a good time.
Well the FenSens Wireless Parking Sensor ($100) solves this problem with a simple battery powered license plate frame. Installation takes about 5 minutes and all you need is a screwdriver. Remove your old license plate frame and install the FenSens with its included antitheft screws. Install the FenSens app on your smartphone and pair the license plate frames with your phone. Once installed you get visual and audible alerts so you can park like a champ.
