Alright so I recently installed 6k fogs and wanted my headlights to match and ordered 6k Xentec HID bulbs. So I put them on today but only on side fully turns on. It is not a ballast problem because I tried 8k one time but same issue. If I go back to the stock bulbs they work perfectly and always fire up. I getting frustrated here cuz I have to flicker the lights off and on a few times for both of them to fire up. Any help is appreciated. Ohh and nothing wrong with the fuses either.

2012 G Sedan

 

Had the same issue with some 5k bulbs on my 2011. Was told I might have to use other bulbs.

 

what brand are the bulbs? try the Philips Ultinon

 

Use a different brand bulb. I've used xentecs in the past on my truck and they're absolutely horrible IMO.

 

always remember people, nothing beats the output of stock 4300K's anything more than that, you are losing output..

also, you get what you pay for with HID bulbs..stick with the brand names, Hella, Philips etc..

 

+1 ^^^

with the exception of Osrams CBI 5000K, which are just a little higher output than OEM 4300K, while burning at 5000K and providing a whiter and more even output pattern.
