Some delightful beggar has punched a hole in the rear light lens. Looked up the part and it seems that I have to have a complete light unit!

Can anyone confirm that I can't just get a lens?

How easy would the whole unit be to fit?

 

TIA

Can't say whether the lens cover is a separate item, I wouldn't think so.

Get a replacement from a scrappy, should be a 5 minute job with a minimum of tools required.

I think that the part number differs between pre-FL and post-FL models.
