Doghouses at Side Signal Only Intersection

[traffic light guy]

Cool photos! I don't think I've seen a 3M bimodal signal before, at least not in this area. Are they common in some parts of the country? I may have seen one in BC, since they only use bimodal signals, but I can't think of an example at this moment.

We used to have a lot of them in the Joliet area.  Most any intersection (pre-dating 1985, and not having an aluminum truss) had them for the left turn movement.  I wish I could find a photo of them somewhere, but have had no luck to date.

They were a follows:

Red ball - standard round
Yellow ball - standard round
Green ball - standard round
Bimodal arrow (green/yellow) - 3M programmable

Something along the lines of North Star's 3M:

Yes, similar.  We had this under a regular three bulb signal: https://www.youtube.com/watch?time_continue=1&v=PLKCkurQ8T8

I should've known Rockford wouldn't fail me for finding old signals.  Found this one in Rockford, IL.  It's exactly what we used to have all over Joliet: https://goo.gl/maps/zaGw972MABF2

Thank you for sharing that. I've always wondered how those old bi-modal signals worked. Seems so obvious now.

Interesting how far the bi-modal signal is from the green orb. Almost like they tacked it on well after the fact.

That signal is tough. Very creative how it has a motor in the back, so the indications can change color

Though not strictly a side signal only intersection, there is this ground mounted 4-section & doghouse combo on Saville Row at Pine Chapel Rd in Hampton, VA

In the opposite direction (coming from that parking lot) is a 4-section & a normal 3-section

That's normal, PA does this a lot too

This side-mounted assembly is at the intersection of OH-795 and Lemoyne Road.  Doghouse is used in the median on the eastbound OH-795 leg.  This assembly exists as a side-mount because of Toledo Executive Airport's location on the NW side of the intersection.  Have to make sure no low flying aircraft hit a signal assembly.  How uncommon is it to see?  There is a flasher heading eastbound with a signal ahead sign and below it is a "SIDE MOUNTED" plaque underneath it!

Never seen that type of sign before. But a great setup! Reminds me of Wisconsin, minus the trombone assembly.

Indiana 67 at Camby Road has not one, but 2 on the SW side of Indy.

If an airplane hits a traffic light which is 16 feet high, 700 feet from the edge of the runway, there's a bit more to worry about than replacing the traffic light.

And there's numerous examples of traffic lights close to runways, so "not to confuse the pilot" isn't an excuse either.
