Unfortunately the optical design hasn't kept pace and so the

opposite directions can be as little as 6 feet and the combined closing speed

can be 40mph+.





There are two possible solutions:


2) Use a bright light that has an ultra-low spill design - like a search light.

I'll be able to see the road and nobody will be blinded.

Another approach would be to use the bright LED but direct the light thru a tube with a b]ack inside to reduce the spill. Maybe a piece of electrical conduit, a piece of pvc pipe, a piece of copper pipe. Or to prove concept some black paper.
