Animating the old Michigan Left Turn displays. The Flashing Red Ball was law for permissive left turn in Michigan from 1975 till 2009. The animation reflects the Oakland County custom 2070 controller software with a faster rate flashing red.
Yes. I live in Michigan these were all over in some style or the other. Most counties used SE-PAC driven Eagle software that had the normal flash rate. Only Oakland County used custom software like this.
even though i dont live in Michigan, but TexDOT use Michigan Left turn on US 281 Pass Loop 1604 but the red dont flash
before it was a jam, so they come up with a low cost but effective transprtation improvement saving 20 mins of travel time
of not being stuck behind left turners
what is thAt grey box? we have them here on the lines too, do you have any pics of the lights inside the left turn illuminated panels? (I'm certain they are MV )
Grey box is a splice box that feeds in cables from the cabinet, and ties them in with the signal cables. I dont have pics of the inside of the case signs. I have seen them both mecury vapor and flourescent. The new ones are LED, or empty...with the front having sheeting on it
the ones we use in MI are Mecury Vapor. I actually have of picture of me holding one I will upload later but the lights and equipment were pulled from it.

Exterior:
Inside, I believe they used 250w MV. Anyways you can see the lamp, diffuser screen, and the F-Can ballast for it.
how much is this going for on ebay?
