my left headlight is out, so I went and bought a bulb and put it in today, only to find that the new bulb won't light, either. and the original bulb doesn't look burnt out. I connected the bulb up hanging loose to make sure it was plugged in properly.

I checked all the headlight fuses in the engine-bay fuse box. the right headlight is fine.

what should I check next?

thanks

 

If the bulb is ok and the fuse is ok, sounds like it is something in between, so how does the harness look? Any damage to it? Can you take a line tester and tap the headlight fuse to see if it is actually getting a current through it?

 

switch the light bulbs.... it maybe the ballast or the relay good luck

 

the cord to the connecting the bulb plugs into looks fine. I don't have a line tester, unfortunately.

I'm guessing it can't be the relay, since there is only one relay for both headlights, and one of them works. does that sound correct?

that leaves me with either replacing the ballast, or looking for a short somewhere (i.e., getting a line tester). right?

thanks

 

If you have HID's its' the Ballast. I had the same issue, got a Lexus ballast of ebay (same Koito part number) for $100.00 and had to hack my headlight to get it in but overall it was pretty easy. It just connects right up but the problem is they put the ballast in before putting the headlight together. I have a thread about it somewhere.

Edit, you have a Touring so you do have HID's.

Here it is.

9k to the rescue!

that sounds like pita. good luck!

 

It wasn't that bad. A hell of a lot better than paying $1300.00 for a new headlight.

 

thanks for the info. I went and ordered a ballast for $136 including shipping (from oembulbs.com)
