I know all diodes actually emit photons, but this tiny glass Zener is
the first one Iv'e seen actually glowing LED red. Is it bad?

How do you know its supposed to be a Zener and not an LED?
As Rono pointed out surface mount LED's are common on PCB's and are intended
for the eyes of the service technician.
