In West Hollywood, one turns left from Santa Monica Blvd. onto La Cienega
Blvd. by veering right onto Holloway, then turning left onto La Cienega
(Santa Monice veers left at this point).  Sort of like this:

---------------------|   |---------|      |-------------

Coming home Sunday morning early, I encountered the sensors marked S
in the drawing.  They were mounted in the middle of the pedestrian 
crosswalk, and you could only activate them if you illegally entered
the crosswalk.  Of course, at 4AM I did, and my 480 pounds of metal and
plastic (Suzuki GS650G) didn't cause the light to change.  Fortunately,
a car came from the other direction on Holloway soon enough to solve the
problem before the Sheriff's patrol could catch me running the light.
