Just get a giant spot light and mount it on your spoiler and run a switch inside your car. problem solved!
No but I don't think it will engage it into reverse if your going like you said, over 5 mph..As far advanced as cars have become i think they would not leave a simple safety thing as such off a car..
I just dont see why you need to "flash" people behind you?? If they are directly behind you and bothering you..mash on the brakes?
