This has been reported many times. Some replacement puddle lamps interfere with the transmitters. Mine don't, possibly because they have a metal body that prevents them from transmitting radio frequency interference. That's odd, since the OEM are plastic, but they may have internal circuitry that accomplishes the same thing.
