Automatic headlights - Sensor adjustment?

[my09denali]

probably voltage related, LED & HID use very different voltages. was this is a kit? or just plug-n-play bulbs?

Diode Dynamics $200 SL2 Pros. Plug and play. Their website says no electrical issues. Tested and confirmed. Virtually impossible to install. The collars not remotely the same. Bright but otherwise junk.

mmm, somethings not adding up here, you had HID's? not in a projector housing? on a 2017?

Have you replaced any lights recently? Started having same issue with my 17 denali after replacing the low beam HID and going to Diode Dynamics LED high beams. Low beams come on way too early. Bigger issue is the high beams will go off for no reason. The "A" in the dash goes out and high beams will be off. Highway driving county roads and its pitch black and the highs turn off. Defeats the purpose of going to those led high beams. I doubt it is a coincidence.

No new lights since I bought the truck in 2022

No I replaced the stock HID low with new Orsam Night Breaker HID and the stock halogen high beams with the diode LEDs.

sensor could be funky, not hard to replace you just have to remove the left & right pillar covers and then the front section of the dash top pops up and you can access the sensor, I am pretty sure anyway if not then you have to pull the radio out which is a bit more trim removal but not hard to do.

I agree.

Even if the sensor is functioning, it might be possible that it slid out of the mount bubble and is just far enough down that it can sense light, but only if very direct. If you can easily get to it there may be value just seeing if it’s loose or low.

Shine an LED flashlight on it. Will probably go to daylight and switch to night when appropriate. Just a thought.

I assume the headlights, the whole dash stays in night mode with super dim instrument panel and even my Car play changes to night node.
Is that helpful?

I timed mine the other day and it took over a minute of consistent daylight to switch back. Is yours taking longer than that?

Mine does the exact same thing….has since day 1 when I bought it new. I guess I’m just used to it…and it doesn’t bother me..

That sounds right. I guess I am just used to the Mercedes GL450 I had before that would switch in a few seconds
