Mandate all new vehicles brought or made in the U.S. to have rear amber turn signals like they are required in Europe and elsewhere in the world besides here in North America unfortunately. I understand that either red or amber is allowed in America, but only amber should be used!
Amber turn signal is much more visible (both day and night), safer, and much easier to not confuse, and being easily able to distinguish from break and back lights. Amber turn signals is also much nicer.
We do understand that some vehicle models do have rear amber color, but make sure that all do and not only some.
According to research and statistics; vehicles involved in less rear accidents with amber rear turn signals than with red color just like the break lights.
