Headlight cracks

[Pyrrho]

When I worked for Apple we had special training to identify types of damage to glass to determine if someone's phone that was brought in would be covered by warranty or not. Observed damage is consistent with excessive heat/cold stresses on the lens. You already have a set of Darlas on the bike -- or were they installed after the incident?

Regardless, glad to hear you picked up a relatively inexpensive replacement from Max BMW. Maybe treat yourself by upgrading your Darlas as well?
