Same here ... hardly ever use them since I don't drive the car in weather that would require them! I have two sets of the plastic Lucas covers, a "round eye" set to display with the car at shows and a "rectangular eye" set for general use when driving the car just for protection of the lenses ...
Were these lens part of original equipment? I've seen a few on eBay but was not sure they would fit. Thanks
Here are some pics of the correct NOS Marchal 656 lights.
