US: FAA issues warning about holiday laser lights

From a November 2017 press release by the U.S. Federal Aviation Administration:

Enjoy Your Holiday Laser-light Display Responsibly
Each holiday season for the past several years, the Federal Aviation Administration (FAA) has received reports from pilots who said they were distracted or temporarily blinded by residential laser-light displays.

The FAA's concerns about lasers – regardless of the source – is that they not be aimed at aircraft in a way that can threaten the safety of a flight by
distracting or blinding the pilots. People may not realize that systems they set up to spread holiday cheer can also pose a potential hazard to pilots flying overhead.

So if you’re going to install a holiday laser-light system, please make sure the lights are hitting your house and not shining up into the sky. It may not look like the lights go much farther than your house, but the extremely concentrated beams of laser lights actually reach much further than most people think.

If the FAA becomes aware of a situation where a laser-light display affects pilots, we start by asking the owner to adjust them or turn them off. However, if someone's laser-light display repeatedly affects pilots despite previous warnings, that person could face an FAA civil penalty.

Note: The FAA press release was reprinted in a number of news sources including KUSA, the News Tribune and SFGate.
