I have seen at least one narrow road on GSV which had a set of traffic lights like this:
Code:
oo
oo
<>
mounted on one side of the road facing into a tiny opposite side road, as well as the regular "green ball" lights at either end.
I don't remember where it is, though... but it's most likely I found it by following a link someone else posted here in a previous thread about the same subject.
The main reason I remember it so well is it seemed so over-the-top to have a 6-light set for such a tiny tiny road
