Denali LED headlamp brow flickering......

[Mark L]

I have a 2014 Denali and I've been having problems with the front headlamps and the LED brows flickering when I hit the unlock button.

 

This had previously happened in the past, but only on the passenger side. My dad just borrowed my truck and I noticed on my security cameras when he hit unlock, both headlamps LED brows started flickering constantly until he started the engine up.

 

Anyone else have this problem or know of a fix? I dread going to the dealership, as the last 2 times they had my truck from 9AM - 5PM each time, once for a free oil change and the next time for an airbag sensor warning light.

 

Thanks-

You sure it isn't a video illusion? Every time I've seen a video of someone's led lights they seem like they flicker.

You know, I was just thinking about that.

 

I'm going to go look at the footage again and see what it shows. It's almost like the old CRT monitors when you'd film them on camera, those flickering lines.

 

Thanks for the reply.

On my 14 Denali one of them was not as bright as the other .

if you were watching it through recording, then it was just the screen refresh rate making it look like it was flickering. LED's are actually blinking extremely fast, our eyes cant tell. But when played back over a video recording, the camera can't keep up like our eyes and results in a flickering.

Thanks so much.

 

Finally glad I figured this out.
