I have a 2008 Euro Accord which has a courtesy light problem-If I close any door with the key still in the ignition,the light functions correctly (stays fully lit for a period then slowly dims to fully off) if however I remove the key from the ignition,the light stays fully lit for a period,dims to half light and stays there without going fully off-the net result being a flat battery if left for 3 days or so.Would anyone have any experience of this or an idea as what might be causing this and how to fix as its a bit of a mystery to me.Thanks.
