Some intersections have left on green arrow only. The red arrow signifies you can't.
The problem with the Red circle compared to the red arrow is that the red circle signifies 'stop' entirely. Not just one way. No where in the vehicular code is there a 'light per lane' rule. So, a solid red means stop. And stop always trumps go. Just a blip in the rules that is finally being corrected. If there's three lanes (one left, on thru, and one thru-or-right-turn) and three lights, they're supposed to all work in tandem with eachother. There's a reason there's a green arrow instead of giving a third solid green for turns. Why? Because it signifies specifically just for the left turn lane.
It didn't always used to be that way. Hell, it took a long time before the left turn signal became a standard.

Everywhere that I've seen them they have a bunch of the individual lights burned out.
Part of the beauty of LEDs. The diode has a long half-life. But, they also have a failure rate, just like a bulb (although much longer). The thing is, instead of one bulb out of one blowing, it's one diode out of 20+ going. If it's a regular bulb, a repair would need to be made immediately. At a much greater cost. One diode, or even a few, is inconsequential to the operation of the light. And it's a hell of a lot cheaper than incandescent bulbs. And the technology is improving. It won't be long until most roadway-related lights are switched to LEDs, including headlamps.
