A recent snowstorm in Reno, Nevada has highlighted a major design flaw with the city's new energy-efficient LED traffic lights. The LED bulbs do not generate enough heat to melt snow and ice that accumulates on them, effectively making the traffic signals and crosswalk signals invisible to motorists. This poses a serious threat to both drivers and pedestrians, increasing the risk of crashes. While the city has begun implementing a solution, it will take time to fully address the problem across all intersections.

Why it matters

The switch to LED traffic lights was intended to save municipalities money through energy efficiency and longer bulb life, but the design has created a dangerous situation for drivers and pedestrians in winter weather. This issue highlights the need to carefully consider the full implications of new technologies, especially when it comes to public safety.

The details

The LED traffic lights in Reno do not get hot enough to melt snow and ice that accumulates on them during winter storms. As a result, the lights and crosswalk signals become completely invisible to motorists, greatly increasing the risk of crashes. The city has started installing new traffic light designs with hoods to prevent snow buildup, but it will take time to retrofit all intersections.

  • A recent snowstorm in Reno, Nevada this week exposed the issue.
  • The city has begun implementing a solution, but it needs more time to fully roll out the needed changes.

What they’re saying

“The new ones have a hood, so snow doesn't accumulate in it. There is no bottom in it. So, the snow just drops out.”

— Tim Hendricks, City of Reno Streets Division

“Unfortunately, with that we haven't been able to change all of them. This is nothing new. It is one of those things that, it depends really on the way the storm comes in and the winds blowing.”

— Tim Hendricks, City of Reno Streets Division

What’s next

The judge in the case will decide on Tuesday whether or not to allow Walker Reed Quinn out on bail.

The takeaway

This case highlights growing concerns in the community about repeat offenders released on bail, raising questions about bail reform, public safety on SF streets, and if any special laws to govern autonomous vehicles in residential and commercial areas.
