Hi all - my DRL LED's went out and are non functional. I noticed them flickering (from a reflection on a trucks bumper) and now it's entirely not working.

Question: Is there a bulb(s) that I can replace or are they built into some sort of internal LED board where the entire headlight needs replacement?

 

bring it to the dealer it's still under warranty.

 

Been down that road, this headlight had condensation in the past, which probably got to the DRL, just want to know if it salvageable by replacing the DRL

 

Lucky for you these headlights aren’t sealed with perma-seal, which is a pain to work with to open up headlights. The LEDs are SMDs on a ribbon cable however if moisture got in, the LED driver is more likely the problem. You could probably buy a salvage and swap the LED driver, it’s a small circuit board fastened by screws and plugs into the LED array and the headlight ECU.

 

Awesome information, thanks so much - exactly what I was looking for. Question - are the DRL LED's managed by the headlight ECU/Ballast?

I'm wondering if mine is fried. All other functions (headlights, high beams) work normally.

 

All power for the headlight goes through the headlight ECU. It provides power to the LED driver inside the headlight. The ECU is not inside the headlight, it's a water tight module just outside of it. I would hope it's not the ECU.
