I figured that wasn’t the issue, but crossed my fingers anyways before I asked if you had checked that.
It may be something that the Bond team could benefit from knowing - I have a couple Bridges myself, and haven’t personally experienced, or heard from anyone else here on the forum, about failing LEDs.
At least it’s (mostly) cosmetic in that the Bridge still works, but definitely strange and unexpected. 
(I’m mostly joking, but Trial Master might want to trade you, haha)
