my 2015 GS350 3yr lease is due end of september.
recently my passenger side low beam wont work. (it turns on and goes off with in 10sec.)
is it covered under warranty or do i have to replace it?

 

Maybe your headlight bulb is almost dead and just needs to be replaced. It's odd that it turns on then off. Then again I've never replaced an hid bulb because it died so I don't know of this is a common symptom when the bulb is on its last days.

 

Could be a bad ballast. I've seen this happen with aftermarket hid bulbs.

 

its stock everything from the factory.
factory bulb dies in 3yrs?

 

Sounds like a bad ballast to me.

 

if it's bad ballast, would it covered under warranty?

 

The ballast will be covered under warranty. The bulb may not be.

 

If you are still in the Basic Warranty period...

 

I would assume so since your car is only 3 years old.

 

if its dead bulb, its not covered under warranty?
anything you guys recommand buying?

 

I would think any D4S 4300k bulb will work. I looked for LED bulbs nothing found available for replacement. I'm looking to match aftermarket LED 6k fog lights and hope something comes up.

 

Has anyone changed out only one bulb? There seems to be a wide range of D4S bulbs available that will "fit" but I'd like the color to be the same for both headlights. Do I need to spend $150 for the Sylvania bulb suggested by Advance Auto (which I've been unable to independently verify as OEM) or will a $44 Phillips bulb match and last as long? 2014 Lexus GS350 AWD (not F or F-sport). Thanks.
