How do I tell the car behind me to turn off their high beams!!!?

I can't belive how many inconsiderate drivers are on the roads. Is there an product that can redirect the light beam out of my eyes, and back to the driver behind me?

Oh am with you on this one or they drive with there fog or extra driving light on coming at you and it is a against the law but they still do it, well there is no safe way but i use my windshield wiper sprayer and trust me on this they will change lanes, and will work up to about a 1/2mile or more, then u get the finger but it better than flipping the leaver on you center mirror but that does not help the side mirror's

Yes, thee is such an invention. It's called a rearview mirror. You can adjust it to redirect the headlamp beam from the car behind you back to the source.
point a laser at his eyes to show him how it feels
Slam on your brakes causing them to hit the rear of your car, that will surely do the trick! No, just kidding, try as I have . Carry one of those new Hi-Power LED flashlights and flash them, they are quite brite and will alert the driver, if they are thoughtful and considerate they will notice and turn down there lights.
The proper signal is to wave your hand side to side across the rear view mirror.

However dude, calm down. Life is to short to get all riled-up because some dumba** behind you forgot to dim their lights. Try the signal a couple of times, chances are they will see you and dim their lights.
Slam on your brakes!
Pull over and let them pass you. After they are in front of you flash your high beams at them a few times so they turn theirs off. If they become the lead car by you doing this they should realize that they just beamed you and be more considerate if they get behind someone else.

That's how I resolve the problem anyhow. Hope I have been helpful
CARRY A MIRROR AND HOLD IT UP TO REFLECT THE LIGHT BACK AT THEM
I just keep flashing my brakes at them, they usually catch on!!
