I made one Lense courtesy light prototype for my X1/9 1979 is been located on the middle of targa column. This is my spare part and has on/off mechanism.

The lense courtesy light prototype for late years (located on each door)

Both are almost same, so I made one mould for both.

I have some technical problems, some minor bubbles but looks good, made on polyurethane as well…

just follow pictures.
