Well from what you've said there I gather that it would cause a data error. Which brings you to the TCP/IP protocol and whats called the 3 way handshake which is the way TCP error checks
, in essence the dodgy light would cause an error and the computer recieving would send a message saying "Send me that again it wasn't correct"
