How strong does a light attachment really need to be?

My sense is that the weak point in most light attachments is where the (potentially plastic) mount fits to the rail, or where the (potentially plastic) body of the light fits the mount, not where the rail attaches to the gun.

It also occurs to me that any blow which would break a light mount would probably break the light itself.
Most good lights, especially those designed as weapon lights have fairly thick aluminum bodies and are quite robust. They don't break easy, even if you slam them around. the mounts that are worth using (i.e. not airsoft junk) will also be aluminum. So, in fact, the plastic standard handguards would be the weak point.
