Activating a klaxon light via a terminal

[HuzzahBritain]

Hi everyone,

 

So I'm trying to add an option to a terminal that I'm creating which activates the klaxons placed in the cell, along with the accompanying sound. The problem is, however I'm unsure how to do this as lights seem extremely complicated when taking a look at the script they come in. I was wondering if anyone had already done this / knew how to do this and would be happy giving me some pointers.

 

Thanks!
