Flickering Cargo 3rd brake lights?

When I open my door the cargo portion of the 3rf brake light will flicker sometimes. Sometimes it doesn't. They are factory led I think? It's a 2019 limited with low miles. The rest of the truck is led except the map lights and no issues anywhere else. Anyone else seen this happen?

 

Mine did the same thing. I think it was the cheap LED’s that I used. Eventually one burned out, so I just shut it off. Never really used it anyway.

 

It is the LED bulbs. Just replace them. I just replaced one of mine. They were about 4 years old. My bulbs are 921s. Probably no change for 219 but you can look them up in the manual.

 

Thanks guys. First car with leds so wasn't sure what was up. Did they come factory with leds? I will just replace them anyway but trying to figure out if they put LEDs in the whole truck except map lights from factory or if someone did that. Thanks again
