As long as the rules are met nothing is specified in any regs about incandescent vs LED. Whether or not an LED will meet the visibility requirements in a fixture originally made for incandescent bulbs is the users responsibility to determine. The manufacturers only test for compliance using their prescribed bulb so using and LED would no longer be certified by the manufacturer.
