2005 GMC Yukon Question: Third Brake Light

Regular brake lights work fine. Third brake light does not work. Is this a bulb replacement issue or a fuse issue? -
Answer 1
More than likely the bulbs is the third brake light is bad -
Answer 2
I have the same issue with mine. Assembly is multiple LEDs so appears to be not getting power. need to take some time to put a meter on to confirm. -
