They don't, unless the voltage regulator is built REALLY badly. Temporarily wrapping the lights in Aluminum foil that's grounded to the truck would shield them and prove if it's RFI. And LEDs are already diodes, so adding more diodes won't change anything. I'd try adding a noise filter capacitor across the power & ground wires to the lights.
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.
