Purple "Rain" – LEDs casting a purple glow on Oregon Highway 34
If you’ve recently driven on Oregon Highway 34, you may have noticed the street lights going from the typical halogen-type that cast the nostalgic “yellow” and buzz noise have been replaced with the more modern LED-style light.

At a Glance: What: Purple “Rain” – Purple LEDs casting a purple glow on Oregon Highway 34 Why: A manufacturer defect in the LEDs The Cause: LEDs naturally emit blue/purple light. They are typically covered in a phosphor coating to turn that light white. When the coating degrades or fails, the original purple hue leaks through. What’s Next: Replacing the affected fixtures in the next 10-12 weeks is estimated at $20,000 for time and materials.
