Azaghal and the Dwarves of Belegost saved the Noldor of Middle Earth and prevented them from being wiped out by Glaurung. Azaghal displayed as much courage in his wounding and driving Glaurung from the field as Glorfindel facing down a Balrog. The level of courage would be the same and dwarven stubbornness simply replaces seeing the light of Aman. So that could only mean seeing the light provides some magical quality that makes a creature of terror vulnerable that wouldn't provide an advantage against a more natural foe, if say Turgon and Hurin were to face off.
