OK so today, I installed a Garage Stoplight so that I wont constantly have to be worried about EXACTLY where the front end chin spoiler is in relation to my workbench that sits on the back wall of my garage. Here is a short YOUTUBE video below on how it works. You can pick up one of these at HOME DEPOT for about 32 dollars.

The picture below gives you a view on how everything is set up on my workbench. You can see the sensor that is below the light that gauges how close my bumper is and THAT's what controls the light. In this specific instance, the sensor will bounce an ultrasonic wave off my bumper bar.
