Given that, around here anyway, solar powered "night lights" for use outdoors are very prevalent and only set you back about a dollar a piece... $5 certainly seems very possible.

Now these lights I'm talking about are really quite dim (and omni-directional), but they really are disgustingly cheap as well.

A product designed to be of practical use rather than almost purely for decoration, and at 5x the price point, would most likely fare a lot better.

Edit: Would "likely" fare better? Obviously it does. I seem to have lost track of the point I was trying to make, namely the price. XD
