Just bought a 06 and the left headlight turns off after a few minutes or Right side... The Fogs are HIDs aswell i doubt thats the issue tho..... Im thinking old bulbs or needs Capacitor????
Whats stock hid on GS300 ? should i go with 6000K?

On my S-Class Benz and i had to use the HID Capacitor so i didnt get flicker/turn off's and codes... With aftermarket HIDs on a GS do i need Capacitor??

 

I think stardard is 4300K on GS. Some people are running 6000K and it looks good.

 

Well, you're saying that both the left and the right headlight turns off. This does not sound like a bad bulb to me. Does this problem only occur with the fogs on ?

I have HID fogs as well, and all I did was changed the fuse to 15amp. I did not have to add anything else.

Stock is 4300K, 6000K would look nicer.

 

I have a 06 gs and am experiencing the same issue. The left or right will go out. If i turn off the headlights and then turn them back on the issue will go away for a bit.

Were you ever able to get this solved? I don't have the fogs on when this is happening just the headlights.

 

Go with Philips Ultonian 6000k D4S hid bulbs...you can't go wrong w/ that setup
