They seem to fail at the slightest hint of rain. Like literally it could be lightening 10 miles away and boom it goes out and it doesn't seem to matter where you are. It seems prevalent around the Lakeline area, as well as Parmer Ln area (especially around Apple), sometimes on F.M. 620 (around Lakeline & Anderson Mill area) and also up and down U.S. 183 between Cedar Park and Leander. I just can't help but wonder why that is, they reinforce them from wind by mounting them Horizontally but they just do not like storms at all.

I know some of them are programmed to deactivate during non-peak hours such as the ones in Lakeway and a few up and down MoPac and also 1431 and 2243.. ..but do they have some sort of inherent weakness to storms? They seem much more prone to failing than most I've seen around the nation.

The ones on 360 seem to go out a lot.

I’ve been here five years and have the same question. It never happened in San Antonio.

Possibly but some of these are also fairly new signals, well I presume atleast, I don't think the ones at Apple are that old... and the ones in Leander around the end of 183a can't be that old.

Signals get their power from the power company. When the power goes out in an area, the signals also go out. Some newer ones have battery back-up, and remain on for several hours.

Often an LED signal lamp totally fails as a result of a power surge due to lightning or a power failure.

The one on 183a @ San Gabriel was out all weekend, but was in a flashing red state for all directions.

Primary culprit: Texas' grid doesn't really prioritize undergrounding electrical lines. This makes the grid more prone to incidences. It is cheaper to build at least.

If you look at the bottom of this page, it looks like electrical maintenance is contracted out to The Levy Company, Inc. There was either a miscommunication between CTRMA and them, or the power draw or signal cabinet got fried and it took a weekend to get the replacements shipped in.
