PHX31, here's a link to an earlier post by 'Los Angeles Past' that you might find interesting.

Sopas_ej had also posted a very cool photo of a stop sign that was actually embedded into the middle of the roadway.
If I'm not mistaken, it lit up as well.
Do you remember this sopas_ej? I looked for the post but was unable to find it again.
