First I must say that I am new to the sight and addicted... I Purched a few Dept 56 North Pole series houses that have this plug..one was Robbies Robots..the other Peppermint Petes..the auxilary runs the LED lights on Robbies and the spinnng wheel on Pete's....now my problem when I turn them on..with the auxilary part clipped in and the bulb turned on..the bulb will not work...at first I thought it was a bad bulb..so I got a new bulb..same thing..tried the bulb in a window candle..bulb works fine..so I tried a new cord set thinking it was a bad bulb socket...nope..same thing on other cord set..so what am I doing wrong??? is there some trick to these???...and those auxilary clips are horrible to unclip when trying to unclip..I feel like I am going to break it..please help!!!!!!
