How do you know which LED bulb is bad on Christmas lights?

Simply bring the light tester close to each bulb. The tester’s indicator will light up when it’s near a functioning bulb. If you have a non-contact voltage detector, bring the detector close to the wire section between each bulb to test for voltage. The dead section of wire will be the section after your bad bulb.
