I've tried Googling for Japanese/Japanese dictionary definitions of this phrase, but can only find usages so far, which haven't helped.
More context:
"俺たち職人の腕が光る"
I think from context that the speaker is saying "so that us artisans do well / look good / show how good we are", or something in that area, but dictionaries haven't been helpful so far - hoping Japanese StackExchange can solve the riddle!
Thanks.
