Interesting observation, though would not opening - vs. closing - the door
have been unaffected since the light would have been off before opening, unless
the door had recently been operated? Those bulbs aren't on at all times, are
they?

Subject: [RFI] Garage Door RFI
For years I've easily opened my garage door with the car's remote system
from 400 ft. away. A few weeks ago I noticed that was no longer
possible. Even from my own driveway it was often hard to open it. I
had installed a couple of 11w LED bulbs in the main motor unit. I had
no concern, since I have 35 Cree LED floods in my house that do not
create noise beyond a few inches. This was different. Those bulbs
generated noise in the 300Mhz spectrum that interfered with the
reception from the remote. Replacing them with 23w CFL lights solved
the problem. Beware of LED lights in a garage door opener!!!
