Honda Nos item fits various models I have a Sl100 here with this lamp fitted but on checking it says it fits a C50L as well so you decide. Has rubber gasket but no screws to secure the lens part no on the label is 33701-gb4 600. Lens came separate but doesn’t say Stanley but made in Taiwan .

Although it all came from a guy in Australia years ago along with a lot of other parts I bought!

Any questions please ask.
