Individual LEDs are usually narrow angle, and although the stop/tail versions
I have seen use an array all the elements point straight back. They seem to
have missed a trick by not fanning them out and getting a better spread. But
from ones I have seen the tail illumination is noticeably brighter than
incandescent (or that may have been partly due to old bulbs and dusty
reflector) which has the double drawback of not only being dazzling for
following traffic in the wet, but also resulted in their being less
distinction between tail and stop which makes it *easier* for following
drivers to miss you putting on your brakes.

I got some for my motorcycles, and after installing them in two
different bikes, got concerned with how directional they seemed to be.
