take the plastic panels off in the engine bay. get an 11mm socket wrench to unbolt the washer fluid spout to make reaching the driver's side bulb easier. you'll see a clear, circular cover with a star shaped design on it. twist that and it'll expose the plug for the bulb. turn the plug and then the bulb is exposed. there will be a metal clip that you squeeze and swing out of the way. then you can pull the bulb out.

They showed me the grounds with the front end off the car, and even I could see it wasn't good. Bottom line call Robbie and talk to him. They're real good and they are car guys not just mechanics. Wait til you see all the neat racing stuff when you go into the shop. Really cool place to hang out in Torrance. Robbie will give a once over for you. Call them Monday afternoon cause racing season started to day and they were all out at the track up north running the new car. Let me know what happens, and don't forget to tell them "Doc"*sent you.*They will take care of you and won't break the bank..

If anyone been through or know the solution, I would really appreciate it.

Thank you

I absolutely refuse to pay Lexus a grand per headlight to replace ballast, etc. Finally I woke up and remembered my Bud Chris Rado has his own shop in Torrance Ca. called World Racing where he builds his world class Scions under Toyotas sponsorship.

Anyway these guys build their own stuff and think outside of the box. So, I went over and talked to Rob Cardona who is the general manager and a really cool guy. After explaining the symptoms, he suggested it might be a combination of things, so they tore the front end off of my Lexus, examined it and told me first of all the bulbs weren't right, and they noticed the grounding of the headlight assembly was poorly designed, and all the symptoms fit an intermittent badly grounded system too. So they ordered all the right factory bulbs and inexpensive after market ballasts, and reworked the grounding, and installed.

My lights come with a snap, they are bright clear, and no more flicker. If you're in Southern California I'd go by and see them. If not give them a call and mention that "DOC" posted it on the Lexus Forum. Those guys are all young, into racing and Motorsports, and very cool and will talk to you if nothing else.

I have never been happier and they solved the problem. Someone suggested that Lexus wants to sell you the whole thing so they don't have to admit they had a poor ground design among other things. Or as Robbie said, "I bet if you go to Lexus and have them do it, if you tear it down afterwards you'll find they "fixed" the ground defect, but they won't tell you that." Had lunch with Robbie today. Give him a call, tell him "Doc" told you. My lights are kicking *** now.

Hope this helps
