I have had my Lexus for about a year now - and the headlight on the drivers side will intermittently die for no reason.

When I leave the headlights in auto mode - it wont work - but if I move the switch to the headlight on position it turns on.

Is this a common issue?

Thanks.

It's probably the bulb, but it could also be the ballast. I would swap bulbs left/right and see if the issue follows the bulb.

Is it still under warranty? I know you said you have had it for a year. Did you buy it new, or just new to you?
No snese messing with it if you can have someone else do it for free!

The car is new to me - so its only covered by power train.

Do you have to take out the whole headlight to get access to the balast/bulbs?

it is most likely the ballast. weak ballast dont draw enough power to start the bulbs in auto mode. you have to turn them on manually. what brand kit did you buy? remember you get what you pay for. a decent kit should run you 75 dollars at least

oh wait... you HIDs are stock? or you had a KIT?

No you dont. Just remove the engine covers and you can access the moisture sheild that is hiding the bulb/ballast. You need to remove the water tube on the right side of the engine bay. It comes off with a 10mm socket

I have the same problem with my xenondepot kit. I was told I need this relay harness http://www.KBcarstuff.com/HID-Kit-Wi...-p/wirehar.htm

Are your hid's oem or aftermarket?

That will grant you access to the bulb, but not the ballast, which is screwed into the bottom of the headlight.

Oh I didnt know thats how the OEM setup is. I was assuming that he had an aftermarket HID kit

It has nothing to do with the ballasts being weak. It has to do with the operating voltage range is. Furthermore, it depends on how much of a power drop there is in the OE harness when the vehicle is starting.

Best bet is to swap the bulbs side to side. Best chance it is the bulbs.

just had this same problem. i let it go for a while because if i turned the switch out of auto and went back, the bulb would come back on, lol. anyway, after a while it would just only stay on for a few minutes after i started the car and then would only last a few minutes after i tried manually putting it back on. turned out to be the bulb. had both bulbs replaced and has been fine since.
