Looks more like a 3M M-131 signal to me, the McCains have round visors. Wink

I'm pretty sure they are too new to be 3M's, unless they are NOS. It's possible McCains have square visors as an option.

If you're talking about these then they're definitely 3Ms since they have a pointed backdoor. The McCain use a modified 8" signal housing as the door.

I guess they are NOS then since they're quite new though.

Yes those are the signals, in fact it is the exact same one in street view as this one! I guess they must be NOS since they where installed less then ten years ago.

It's a 3M, my friend!! McCain's use a standard door and visor because their stuff is junk!!

3M discontinued the line in 2004 but that doesn't mean they immediately ran out of orders. They were still processing orders and selling parts well into 2009.

Interesting, thanks for that information! Still doesn't explain why they chose the black backplates.

Not too common here but we do have them at some intersections, for some reason they have black backplates instead of the standard yellow here.
