Led taillight issues

[ccautoupholstery]

I order led taillights for my 67 from brothers along with their led flasher. Had no problems for a couple weeks at least, but today an old lady followed me into Home Depot to tell me I have no brake lights. Sure enough, I have turn signals and running lights but no break lights with the headlights off or on. I have verified power all tge way back so I'm assuming something went bad in the leds but I feel like it is weird that they both went out randomly. Has anyone else had this issue?
