I am not following you on what you are saying. There are two parts to a HID set up. The ballast and the bulb. The ballast might be mounted inside the headlight, I am not sure. Most of the time they are mounted in the engine bay some where. They don't have to be mounted to fender. If he has replaced his bulb and it still flickers, it is the ballast. This is a common failure symptom of an HID ballast.

As far as replacing it with an after market kit, I would only do that if you replaced both of them. I would look for a used OEM Lexus ballast first. Could very easy come from a junk yard where I have picked them up for under $40.

btw, I am looking to do a TSX retrofit into my headlights with DSr bulbs and ballast.

I would highly recommend what Salim said as well. You have a good ballast and a good bulb. Start switching them out to find out what the problem is. I see no need in you taking this in to a mechanic. Start switching back and forth.

My Rx300 got hit on the front driver side panel and broke the cover for the headlamp.
The body shop will replace the fender and they told me the whole headlamp unit need replacing since it comes as a unit. The HID light is not affected. Can the headlamp cover be replaced without needing the whole unit? It is $400 used on Ebay and over a thousand new for Lexus OEM.
Please advise.

I think unfortunately you need the whole lamp I never heard of replacing the lamp cover. But you could save the hid bulb, blast etc.

Hey buddy welcome to club lexus i had the same problem with this my ballast died on me the denso ballast is mounted inside the headlight its self if you pull out your headlight their will be a rectangular cover near the fog light bulb with 2 Philips head screws thats where the ballast is at also make sure that the bulb is 100% oem denso ,philips, hella, or genral electric my best luck was with denso i found other bulbs would turn on and shut off, but if you open your hood and here a fast buzzing sound from the side that is not lighting up its 100% the ballast it just has initially Failed on you and a replacement will be needed

I went ahead and ordered a used unit from E-bay for $380. it is freaking expensive for a used and a new one is double that. Thanks,
