Beacon Stem

A while back I had an idea for a bicycle stem that had a light integrated into it.  Of course the lack of angle adjust-ability would make it a somewhat cosmetic piece unless it came with a set of shims for the lens or something like that, but a large flood light for in-town commuting would at the very least look cool and augment the streetlights.

Here’s what I came up with:

So the battery fits into the very large stem body, which would have a piece of high density foam inside to prevent the battery from rattling and being damaged.  A wire runs between that and the face-plate, which houses the light itself, and a lens is affixed to the face-plate, which also serves the shroud the face-plate bolts.

All in all, it would be expensive to make, heavy, somewhat impractical, but really would look cool on the right kind of bike. And that is what matters.
