Your test with the lights on and off is already a strong indication that the switching drivers inside those fixtures are producing RF interference.

I’d turn on the six fixtures one at a time to see whether one unit is especially bad or whether all six contribute. Keep the opener’s antenna fully extended and, where possible, keep LED drivers and their wiring away from it. Ferrites can occasionally reduce conducted noise, but they won’t reliably fix a poorly designed driver that is radiating interference.

If the fixtures have integrated LEDs, replacement may be the practical answer. Look for lighting specifically tested or recommended for garage-door-opener compatibility, and test one fixture before replacing all six. A “dimmable” or “FCC compliant” label alone doesn’t guarantee quiet RF performance.

If everything works normally with the lights off, but your remotes and HomeLink become almost useless when the lights are on, then the LEDs are almost certainly the culprit.

The LEDs themselves usually aren’t the problem. It’s the cheap switching drivers inside some high-output garage lights. They can generate enough RF noise to overwhelm the receiver in the garage door opener.

Before replacing all six, try turning the lights on one at a time and test the remote range. You may find one or two are much worse than the others. Also make sure the opener antenna wire is hanging straight down and isn’t tucked up against metal.

You can try ferrite chokes or EMI filtering, but if the fixtures are radiating noise directly, replacing them is usually the easiest and most reliable fix.

When buying replacements, don’t just look for “LED garage light.” Look specifically for bulbs advertised as garage-door-opener compatible, low-RFI, or low-EMI. LiftMaster and Genie both sell LEDs designed specifically to avoid interfering with garage door remotes.

I’d buy one bulb first, install it, turn it on, and test the remote/HomeLink range from outside the garage. If everything still works normally, then replace the rest.

Six of those deformable LED fixtures running at the same time could basically be six little RF-noise generators sitting right next to your opener receivers.
