The DRL stands for daytime running lights. There is an electronic module that controls the operation of this that is located under the dash, which is probably where your noise is coming from. The noise goes away when you turn your headlights on because the DRL will disengage. I have replaced these before on civics and it should cure your problem. When ordering your part ask for a "daytime running light module". Hope this helps.
