The following algorithm should do it, I think:
    define flag,
    clear flag to start with
    read input
    on any '1' set the output port for the LED and clear the flag else
    read input
    if following input = '0' then increment the flag
    compare the flag with '5'
    as long as < 5 goto read input
    when flag =5 then: clear the flag, switch off the LED
    goto read input.

I guess that you will be able to transalte this in assembler. If not you
have to wait till I can find the time to do it.
