Thanks for the help guys, I turned on the parking sensors, but it seems like only one of my ALP heads is beeping when i put my hand near it. I guess it has never been working because my ALPs have always required somewhat of a distance of clear space in order to start. Here is the video. Not sure why my friend's ALP beeps too sometimes, his parking sensors work.

I guess I will have to send this one back and get a new one.
