How many times have you hit your car in reverse while parking thinking that there might still be some space left between your car and the wall? Well, you would have at least notice someone do this if you have not done it. To counter this problem, this auto LED parking sensor warns you when you are getting very near to a wall or a car while reversing. It does that by the four sensors that are fixed behind the car. You can also choose to install the sensors on the front of the car or even better, front and back both. The sensors come along with all the necessary wiring and other equipment required for the installation and the installation is very easy and you can do it by yourself. The instruction manual that comes along with this sensor will help you through the installation process, so make sure to read it beforehand.
