LEDs are inherently more directional than other forms of lighting.
That is in fact a good thing, because any light that is illuminating
areas you don't *need* to be illuminated is wasted energy. Coverage
angles are increased either by mounting several LEDs at different
angles, or with suitable optics (usually diffuser/lens combination,
which increases the price).

As far as car running lights go, they are rubbish. Look at the angle of
view they disapear at on a Mercedes. It is very narrow.

At night I find the on/off flickering of LED brake lights particularly
annoying, why not have interleaved arrays of LEDs that turn on at
different times to give the effect of a constant light?
