I've got an old Light & Motion ARC light I'm still using. I finally thought to fabricate a shield that simply attaches over the front of the light and blocks light from going upward and blinding oncomers. It would basically be like a visor for the light.

In addition to keeping light out of the eyes of oncoming traffic, it would reflect that otherwise unused upward light back to the ground.

Is anyone interested in one of these?

I'm considering have several water jet cut from aluminum.

If anyone is interested they would probably be around $20 - $30, depending on how many were water jet cut at once.
