2015 Yukon Denali headlight

[finston]

Hi,
This is my first post. I looked but couldn’t find any info on my particular issue. My Denali passenger headlight will not work correctly. It flickers 3 times then stays off. The led running lights are fine. Any ideas?

Thanks
Jason

Check this website and buy Osram or Philips D3S bulbs

Should we assume you’re referring to the low beam?

Yes, that's correct. Low beam. I just ordered some philips ultinon 6000k bulbs.

Well hopefully it’s the bulb and not the ballast. That would be a bigger PITA to replace.

Usually ballast last long, most likely it is the bulb that needs to be replaced

I do agree, but I notice in mine it seems like the low beam HID’s fire up quite often when the headlight switch is left in Auto. I feel like too much, it’ll still be pretty light out and I’ll notice from the reflection on the back of the vehicle in front of me that my headlights are on.

So it’s become a habit for me to just switch them to parking lights during the day so my low beams aren’t on for no reason in Auto headlight mode. Because I know constant firing up and shutting off when in Auto headlight mode can prematurely wear out HID ballasts and bulbs.

I'm not worried about the ballasts running too long, I only drive about 1k miles a month.

Is your truck under warranty?

Congrats,,
So which set of bulbs you bought and use? philips ultinon 6000k?
If so, give us you impressions about the beam and colour output, as well as clarity.

I did go with the philips. I will give my thoughts after I drive at night. So far, this morning at dawn they look great. Color is exactly what I was hoping for.

So driving tonight the lights look good but I noticed a flicker every so often. Not sure what that could mean. Both sides. Maybe alternator?

Make sure the wire is perfectly connected, and make sure the bulb is stable and in place.
I guess this happens when you hit bumps because fitting I guess is not perfect as Osram bulbs.

I have the same issue, but until now I haven’t fixed it. What I guess I would do is to use glue gun so the bulb won’t wiggle as well as the wire

Everything snapped in pretty snug. It’s not bumps causing it bc it happened while parked. I’ll have to troubleshoot some more today. I’m also going to contact HID Concept who I bought the lights through.

Alright, so after driving this morning they flickered a few times in the first 30 seconds or so then stopped. It's almost like there's a warm up period or something. I also turned my ac on and off to allow the compressor to pull power and that didn't cause flickering. So, we'll see how the next drive goes.

How the heck did you remove the factory HID's? I can't get my hand in there to turn them for shit! Any tips cause I have had my new bulbs now for a month and I can't turn the ring that holds them in.

For me I have used a long nose plier
