Combo Traffic Signals

This page features signals with combinations of 12 and 8 inch signal bodies.

All of the pictures below are animated gifs and may take some time to load completely, except for the LEFT turn signal. The LEFT turn signal is a static (non-animated) picture that can be animated by placing your mouse over the picture.

LFE/Automatic Signal 12-8-8 Aluminum signal

LFE/Automatic Signal cast aluminum signal with 12 inch red lens and 8 inch yellow and green lenses. Click on the picture for more pictures of this and other LFE/Automatic Signal signals.

Crouse Hinds Spring Latch/type M (Breadpan) combo signal

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.

8 8 12 Alusig

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.

Here is another left turn signal. The signal is a Marbelite with an 8 inch to 12 inch enlarging unit made by 3M. With this attachment, the normal lens is replaced with a frosted lens of the same color and the enlarging unit is mounted in place of the standard visor.

To see detailed pictures and information about the enlarging unit, please see the
 3M page.

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.
