LFE/Automatic Signal signals.
||Crouse Hinds cast aluminum signal with 12
inch red lens and 8 inch yellow and green lenses. The 8 inch sections
are type M, also known as "bread pan" sections. The 12 inch
section was very unpopular with traffic departments because of the
spring latches that were used to hold the door shut. It wasn't very
water tight and so its life was short lived. Click on the signal to see
more pictures of this signal.
|Alusig cast aluminum signal
with 12 inch green arrow. This signal was put together with spare parts.
It represents what LEFT turn signals used to be like in Michigan before
signals were required to be all 12 inch sections. Put your mouse over
the picture to animate the signal. The only thing missing
here is a LEFT sign above the signal. Some
LEFT signals in Michigan begin a flashing RED indication when the thru
traffic gets a green so that the LEFT traffic can proceed when the on
coming thru traffic is clear. Once the thru traffic is stopped by a red
signal, the LEFT traffic gets a green arrow, yellow arrow and then back
to solid red. When these signals were used in the 8-8-12 configuration,
yellow arrows were not required. To see an animation of this that may

||Here we have a Checker signal.
Checkers are known for not holding up well in the field. This one has a
strobe light in the red section. It is kind of hard to see the strobe tube
in the picture. 8 inch Checker heads look a lot like 8 inch Eagle flat
back signals, except for the logo on the back and the drain holes that
Checker signals have. Click
here to see some pics of the strobe tube and of the back of the signal.
||Here is an Eagle flat back
signal. This signal originally served in Parma, Ohio. The yellow and
green lenses have the same bead pattern as the STOP/GO flagged lenses
that were seen in Eagles of this variety, but the logos on these lenses
are the newer Eagle in a square logo. The red lens has no logo.
