Walking in downtown Denver last night, I noticed a traffic light that was built like the usual red-yellow-green type (in the U.S. at least, I won't to assume everyone uses them), except they were all white lights, the top being a horizontal bar, the middle was a triangle, and the bottom was a vertical bar (I may have reversed the top and bottom, but that makes more sense to me, the bars representing the direction of traffic flow).
Has anyone else seen these? Is it some kind of new traffic light for the color-blind? (It is worth noting, I only saw it at one intersection, and only one side of that intersection had this style of light.)
EDIT: Walked by there again tonight after the Rockies/Red Sox game, and noticed this sign[^], so anyone who guessed public transit was correct.

And go round the bend on the triangle?

I have personally witnessed the exact scenario you described.

They're not quite finished - the circle is still to be installed - but they are so you can drive with your PS4...

That shouldn't be necessary: lights are always Red on top, amber (if any) in the middle, and Green on the bottom. The colorblind use the position as their cue.
The description you have is a bit like railroad controls: 3 dots verticle for GO, 3 dots diagnal for SLOW, and 3 dots horizontal for STOP - no color differences . . . but I've heard they're moving that to the RAG version.
Easiest solution is to close your eyes and hit the gas.

But that isn't always true, I've driven through some areas of Texas where they put their lights horizontally instead of vertically. Obviously if you live in the area position helps, but if you're just passing through, it might not be immediately obvious.

Alas, I knew someone would bring up horizontal. That, too, is standardized, but I didn't know the standard.
Note that if you're in Texass, then all bets are off.

Here (Montréal), I've seen a vertical white bar in conjunction with the other 3 colors.
It is used as a "Transit priority light" to let buses (and maybe taxi) pass the intersection in before all other traffic, just before the green light.
I'd rather be phishing!

Considering the location (near the exit of a major public transit hub) that seems pretty plausible, especially considering it only faced the side where the buses were generally coming from.

It's not a replacement for the standard red-amber-green light. It's a transit priority signal[^] that allows transit vehicles (e.g. trolleys) to proceed when standard vehicles have a red light.

Seconded and fived... now I'm confused... should I have said sevented?

Yes, but only if you're a transit vehicle.

Ah. All my attempts to Google it just ended up with general information about common traffic signs, thanks.

Haven't seen those yet, but:

I had to look up where that is (not a native of the area)...and now I feel a little stupid because the name makes it kind of obvious

Fall asleep at the PlayStation again, did we?
It won't be for colour blindness. Even if you're red-abmer-green colour blind, it's a no-brainer to notice that the Stop one is at the top.

As mentioned above, not all traffic lights are vertically oriented. But I do have a definitive answer, my post original post will have it soon.

I am in SAP training, after seeing their documentation I will never ever swear at the MSDN again. It seems the documentation was written in German, translated to Chinese then to Hindi, then to Spanish and then finally to English.

In other words don't be a SAP. Sorry had to go there!

I didn't know I would have to learn SAP when I took a DBA job. As long as they don't actually expect me to build anything...
