The traffic signals in our area (Central Coast of California) have been
all LED for a while now.  I think the Red was first to be converted, then
an acceptable "green" was found, followed shortly by yellow.  At first,
I was irritated by how bright the "green" ones are, but I got used to it
and I like them a lot in just about all other respects.

Unfortunately, I was just talking to a friend about home lighting and
it's the consensus of her (and her peers) that home LED space lighting
has a long way to go; 10 years or more.  But progress is still being
made.
