Traffic signal lamps for 3M traffic signals.

Traffic signal lamps for 3M traffic signals.

Click to view full size image

PAR 46 lamps for 3M traffic signals. The 75 watt version is for pedestrian signals and is starting to border on unobtanium (3M Ped signals were much, much rarer than vehicle signals). The 150 watt version is for vehicle signals, and is apparently out of production but still available. Also an LED retrofit. Sometimes a tech will forget to disable the dimmer when installing a retrofit leading to a strobing effect. (LEDs don't like current dimming).

Nice!
For some reason as a kid I always liked the square 3M traffic signals
My area only had a few, I think there is still one (Unless it was removed as it has been awhile since I was in downtown Bridgeport, Connecticut)
what does the back of the LED one look like? Also why does the incandescent one have three terminals? I assume there is two filaments?

The back of the LED isn't, IMHO, particularly interesting, a text label and black plastic with the three prongs.

There's only one filament. They used the same form factor as an existing high/low beam 12 volt vehicle light. Some of the LED retrofits omit the third prong or use a piece of plastic.

That LED looks like an Fortel or Electrotech, we have those and they loose rows of 6 and start to flicker, primarily the greens. Yes we had to bypass the dimmer so they wont flicker.

OK so the third prong is just a dummy pin as they used the same mold as the once standard round sealed beam vehicle lamp
Also come to think of it I don't think I have ever seen a 3M Pedestrian signal

3M pedestrian signals are extremely rare and thus highly prized by collectors. AFAIK on the street there's one in San Diego and a couple in DC (the only area to extensively use them). That's it.

I have a red LED retrofit that came with my 3M traffic signal that was made by LeoTek.
