You're as bad as I am , but that sentence was indeed poorly constructed. I should have written "As a birthday present, my wife has requested a front-facing flashing light (for daylight use)."

My only reason for thinking it wouldn't be that useful is that 99% of our riding is on rural roads, with very few intersections, so most of the cars that will see that light will be on the other side of the road.

It came in the mail, and looks good, but we can't try it out until her birthday in October.
