Extreme Cold Triggering LED Headlight Warning Light?

[RL8791]

Update - The headlamps were always properly illuminated whenever the warning light came on. The last two weeks have been in the teens and 20s F and there have been zero recurrences of the warning light coming on. Is it possible that the warning light is due to a greater resistance to the light pivoting if some type of lubricant within becomes too stiff below zero F? I can see this not being a problem with non-LED headlamps which produce considerably more heat - but possibly being overlooked if Mazda re-purposed a mechanism originally designed for non-LED lights.

Anyone know how this is engineered?

I do believe this LED Headlight Warning Light has nothing to do with AFS system, as the AFS system with LED headlights is the same as AFS system with Xenon headlights found on the previous MYs which has no such warning light. Besides, LED generates a lot of heat too which often requires extra heat sink for heat dissipation.

Are you referring to this area?

Disconnect that connector clip and see what happens lol. If you get the AFS warning light simply plug the connector back in and it will go away.

LED Warning light came on for me this past Friday night. Temp was about 6F, but had been down to about -10F that morning. I pulled over and looked them all over, every seemed okay. AFS appeared to be working as well.

Good day, I had this issue - LED Warning Light in January, February and the last time March 1 of this year on my 2016 CX-5 GT. I have had it into the dealer twice now - no error codes appear - I took a picture of the light on March 1 so they would believe me. Today, they would like to replace the "forward sensing camera" however i do NOT have the Tech Package - so i asked them to double check and sure enough they tell me my vehicle has this. Getting it replaced next week.
The LED warning only came on in the cold. Has not appeared again since March 1 - i made sure all the lights were functioning and they were. Has anyone had a dealer replace or do anything to try and correct this issue?

I noticed an amber indicator was lit on my dashboard this morning. I had no idea what it meant as the icon wasn't familiar. I looked it up in the manual and saw that it was the LED Headlight Warning Light. Since my 2016 CX-5 is still under 10,000 in mileage and as it was 10 below zero (F) this morning, I'm assuming the LEDs are affected by extreme cold. Has anyone else had this occur?

I have frozen weapon-lights in the freezer before to see how they tolerated more extreme conditions that I may use them in. They were indeed dimmer, but not bad, and it was likely due to the batteries (even lithiums). I wouldn't think this would cause an error code. I'd take her in.
