The Genie 2-pack LED garage door opener bulbs are perfect for the garage door opener with a 2-light system that has a standard light cavity. Traditional LED light bulbs can cause more problems in your garage door opener than they solve. They can be more delicate and subject to breakage in the rougher environment of the garage and some LED light bulbs emit noise that can actually interfere with radio frequencies, affecting the responsiveness or range of your opener’s remotes. This bulb is specifically designed for garage door openers and creates little or no radio frequency to interfere with openers.
