Installed some cheap ones in my 2013 Pickup for dome lights, and had problems with bluetooth connections with my phone. Replaced with a better LED and the interference went away.
In a home, LEDs can cause interference in some items. Purchase some from Home Depot, and could not use in my garage door opener. Online read some problems with garage door openers and some LED bulbs. Purchased more expensive bulbs and problem went away. Problem was if the bulbs were On, and I tried to close the door from the truck, it would not close. However, if the bulbs were Off, door would close. With the more expensive bulbs, all works fine.
But inside the house, which is 90 percent LEDs (other 10% is fluorescent) I have had no interference with any component.
