I have a 2007 GS350 and my HID lights keep turning off. Its either left of right one goes off within minutes of driving . i can fix the "problem" by turning a light switch off and then back on. But the problems comes back shortly after. Its dangerous at night , cause there is no warning light goes off on the dash when that happens.Does anyone know what this may be . Please help.

 

I had same exact problem, it would only be the right one. I switched the bulbs around n its been good since. I did order new bulbs to change them.

 

thanks , i'll try that . What is right bulb for my car, or where can i look it up.Any suggestions on places to get it cheaper? Unfortunately when i bought my lexus , the manual was missing. 2007 GS350.Thanks

Ive been dealing with this problem for a few months now, always checking off other cars to see if headlight were on......I didnt believe it was just a swap of the bulbs and there problem gone - But for me, Its TRUE... i swapped L-R R-L and it hasnt happen.
So try that and good luck, hope it works for you.

 

I got a set of oem philips D4S 4,300k bulbs from ebay around $90 shipped. Works like a charm.
