I replaced all rear bulbs in the tailight system of my '77 Excella 500. I noticed that there was a thin rubber gasket between the individual housings holding each bulb but none between the lens and the housing. The inside of the lens and the reflector (?) had dust and dirt in each one. While it wasn't extremely bad, did these lens start out with a gasket or not?
