One type of holiday light display is growing in popularity – and it’s attracted the attention of the Federal Aviation Administration.
“People may not realize that systems they set up to spread holiday cheer can also pose a potential hazard to pilots flying overhead,” the FAA says.
Pilots over the past few years have reported being distracted or blinded by residents’ laser light displays, according to the FAA.
Never miss a local story.
The FAA asks that “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 a laser light display becomes a repeat nuisance, the owners can face an FAA penalty.
Laser lights were blamed in at least six aircraft interferences over less than a month in 2015, according to Laser Pointer Safety.
In November 2015, a Coast Guard aircraft sent out a distress call when it was hit with laser lights from a holiday display near Sacramento State, Laser Pointer Safety reported. Sacramento police responded with an air operations unit, according to USA Today.
The culprit? The Star Shower projector, which has a laser that can reach 100 yards into the air, SFGate reports.
