They are WebIDL conformance check errors (I.e., is type conversion being performed as per WedIDL?). According to my reading of WebIDL, the implantation is not conforming - hence 3 errors.

Ms2ger or someone should check the tests to make sure they are ok. 

When I spoke with Ms2ger, Ms2ger suggested that I should not test WebIDL conformance as a better general WebIDL is in the works (though I don't have any details about that project). 

Hopefully the tests are ok and I can remove them once we have a better WebIDL conformance tool. They will do for now.

Therefore, light event should be fired only when "lighting condition" changes. I have not tested the latest Firefox implementation on mobile. Could someone please let me know how often does it fire the event?
