Courtesy lamps in my 2011 laser 655/6

Hi just a bit of advise to all the owners of a coachman laser with courtesy lamps at floor level as we had 2 replacement sets and what happened was when they were left on for 3 hours or more they would over heat and melt ,yes melt the bulbs went black and you could notchange the bulb as it had come part of the houlder / lamp. Many thanks to the manufacturer of the lamps who listened to me and agreed there was a problem and replaced them with diod lamps they look and work great.
