One of the reasons that I want to replace the two that have blown out (far right and right one of the center three) is that it detracts from the appearance of the camper and gives the impression that its not being properly maintained. To me, it is something like a missing hubcap or a broken and 'repaired with duct tape' headlight. Secondly, since I do not move my license plate when I load/unload the camper (it stays on the truck and not easily seen) I don't want to add another reason added for my being pulled over.
Thanks for all of the replies,
John
