I think I've called in maybe two failed LEDs in the last two years or so and probably 95% of Washington County's first-round green Dialight balls (installed late 2001) are still going strong. They aren't as bright as they once were but they still get the job done.

Honestly I'd think cities like Los Angeles probably saw greater cost savings because a majority of the signals there are 12" and those require a higher-wattage bulb than an 8" indication. Correct me if I'm wrong, New Yorkers but aren't most NYC signals still 8"?

Don't get me wrong, the savings and all of that are neat, but they seem to have a greater benefit to southern states than northern ones.
