I saw three (3) riders clip and crash into roundabouts curbs on PBP 2019. One of them said to me, "Merde, c'est le deuxieme fois".....I have seen riders clip curbs and crash in the night on brevets in the USA. They all had one thing in common.
If I were still working and commuting by bike, I would probably have a helmet light as a supplement. That would have to be attention getting. Aside from abundant side reflectors, this is probably OP's best approach.
