I have found the same problem regarding E marking.
I'm using the "old school" Hillman Minx tail lights and finding some that are E marked is IMPOSSIBLE !!!!!!!
So do what I did cast some up with E marking on them.
Find a flat E marked light take a silicone mold from it , cast a thin flat pannel with the E marking on it.
Then carefully remove enough materail from you illegal light and glue the new E marked pannel in its place.
Then simply remold the new tail light in silicone, and once dry ,de mold and cast in clear polyester resin with either red or amble transparent ink to give the correct colour .
Put together and hey presto E marked tail lights !!!
