Just noticed on my 08 GS350 with the adaptive moving beams, the driver side is way yellow compared to the passenger bright white.
I hate to guess the Lexus price for a complete light system.
Anyone have this happen or ideas to check?

 

Might just be the bulb going out. Swap the bulbs side to side. If the "yellow" light changes sides too, then it's the bulb and you can easily/relatively cheaply replace those.

 

That was the first sign of the bulb going out on my car. I recommend replacing both bulbs simultaneously to keep the color of the light matched, because HID bulbs fade with age. Also, if you are thinking about buying OEM bulbs on ebay, be aware that 90% of the bulbs sold there are Chinese knock-offs. Google can teach you how tell if the bulb is fake. One thing you can be sure of: the real OEM bulbs for less than about $80/pair simply do not exist.

 

I thank you guys for the info. These fancy moving light assemblies look a bit pricy and complex..
