Replaced aftermarket under bumper incandescent reverse lights with LED units. Now backup sensor system activates whenever in reverse. Why?

As title says, I had cheap incandescent lamps, mounted under the rear bumper, on my 2000 Excursion 4x4 limited 7.3, for approx. 18 years. I replaced them with these

LED lamps, mounted in the exact same location. The much brighter LED units activate the backup sensor audible tone, every time I go in reverse. Even when I aimed them at the road. I unplugged the lamps and the reverse system operates correctly. Any idea why ? I asked Amazon tech support about it and they know nothing. Thanks.

Thanks. I was thinking RFI (Radio Frequency Interference) , but I do not know if LEDs emit RFI.
Steve83. Might you provide an Amazon link or item number, to an appropriate noise filter cap ?
