Ok I've got my 2006 GS430 drivers headlight that comes on & stays on for about 15 minutes but then shuts off. I've replaced the bulb but its still doing it. If i turn the lights off & then turn them back on the light begins to work again. Can someone please help me.

 

can be ur balast. i had same problem but replaced the bulb solved the issue for me.

 

take that bulb from the driver side that is new, put it on your passenger side. Let it run for 15+ minutes and see if it shuts off again..... The reason for this is, sometimes even if new, bulbs can be faulty. Just like any other freak accident like TVs, Laptops, etc.

 

Replace both bulbs with brand new ones and you're good to go.
