2015 Genesis Sedan hid bulb and ballast replacement

[Gato1]

After much fighting, I was able to remove the insanely tight screw to get to my Hid lights ( one was out). I was so happy with my new 8k (heat wise) lights......but 12 hr later of of my new lights was out ( opposite to the one that was originally bad, I replaced both). My first instinct was to replace the lightbulb again, but it comes on the first time I put the light in. After, (a few hrs later) when I turn on the car, the light struggles to come on. Only after switching the lights on and off a few times does the light finally work. This unfortunately is pointing to the darn ballast. So the question is, do I need to remove the bumper to get the light assembly out? There are 0 posts on the 3,8 Genesis sedan anywhere (utube, etc)

There are videos on YouTube showing how to remove the light assembly. Every video I have seen shows loosening a couple retaining clips (in the fender) and bolts to pull out the bumper a little to remove the the light assembly.

I might have a ballast here I'll sell you super cheap. It was a mis-diagnosis by one of our lube techs. So, it was opened, plugged in, then removed. This is one part that once opened, I cannot return to Hyundai, so I'm stuck with it, and it's been sitting on my shelf for 2 years now. Will need your VIN to see if it's the same part # or not.

Thank you for the comments everyone. After additional research, I will try re- installing the remaining OEM bulb, since it runs at 4500k ( same 12v, 35w as my new 8000k), just to verify the additional heat is not causing the issue. I replaced my old acura 3.2 TL with 6000k HID bulbs long ago and had 0 issues. Maybe the additional k is just too much for the ballast and harness?? I am having this issue on both new lights ( more on the passg side).

The "kelvin" rating doesn't have anything to do with thermal temperature. It's merely a measure of color temperature, which in itself has no correlation to "heat".

If you're not running quality, genuine lamps, you'll have an issue relighting them after a run due to inferior salts. If you found genuine Phillips or OSRAM lamps in 8K, they would probably work fine. The ballasts are generally an all or nothing deal, relighting when hot is much easier than when cold.

Update, so I used 5000k lights this time and they work fine, they are not OEM. Note that the on and off issue I had with the passanger would continue, even after replacing the light a second time with a new bulb. The driver's side was fine 99% of the time, but once in a while would also go out. Something I found interesting was that once the car was on, the drivers hid would usually come on. The passanger's would not, regardless of how many times I cycled it on and off ( ps this is not good for your ballast). If I stopped some place, turn off the car and then turn it on again, both lights would come on. I still believe the 3.8 Genesis system has an issue with the starting voltage for the 8000k bulb (since I replaced it twice with a new 8000k, and both times it failed).

Do you still have that ballast?

Nope, sorry. I did finally sell it in March to a service customer.

Where is the ballast located? My 2015 5.0's passenger side lights are acting up pretty much as above....

Ballast is mounted on bottom of headlamp housing IIRC. Have to remove front bumper cap and pull out headlight.

Thanks - I was afraid of that. Looks like a 2 man job...

Bumper comes off really easy. Headlights hardest part is getting connector on bottom.

Looks like it would... I assume that the headlight assembly needs to removed as well.
