As I see it, the case from the motorcycle turning light is supposed to receive the an incandescent lamp, so the internal diffusions gives its whole area the same brightness as seen from far away.

Wide angle through hole LEDs are often referred to as Top Hat or Straw Hat LEDs due to their shape. The die is close to the external face and the package is often blunt ended to obtain the required radiation tpattern.

We can use this same idea in a smaller way: use a small M&M-sized piece of aluminum foil placed directly in front of LED (glued to inside of translucent cover) to reflect focused light back to the source, and more foil around the led to spread out the light.

A total internal reflection lens with no direct path from LED proper to subject, or a Fresnel lens based "diffuser" will do what you want.

You can get substantially LESS directionality from a typical existing epoxy encapsulated through hole mount LED by simply cutting part of the top off so that the end is "squarish" and closer to the die. In this case, cut off probably all of the domed part and some more. Go down too far and you risk interfering with the LED proper - but you should be able to tell how much you can probably safely remove by examination. This approximates a "top hat" or "straw hat" LED. You can round the edges but this will probably not be necessary. Practice on a cheap LED first :-).
