When we travel with suitcase, the existing 3rd brake light is obscured. So far, no issues (at least so far in CH, DE, NL, B, F & UK) but maybe we've been lucky. Reading various posts, I understand that if I remove the 3rd light, then that's legal, if I don't, and its fitted but cannot be seen, that's illegal.

Is there any issue with securely fitting a flat Rain Light to my suitcase?

Thanks
