2005 Lexus Rx330 Ballast problem??? First I saw my passenger side HID headlight was on and off and then mostly off. I thought the HID bulb burnt out. I bought a new one and replaced it. After I installed it, I turn the headlight on. The new bulb seem like not so bright and about 30 seconds later, it's completely off. So it's not the bulb that burnt out from beginning. My second thought was the ballast which bunt out. I called Lexus dealer and ask them if they carry ballast for my car. Surprised me that they said, they don't know what that is. They only know the wiring harness and the socket but not the ballast for HID bulb. Anyway, could you tell me what's wrong with my headlight and how to fix it. Thanks,

Question edited for clarity

Not easy as it is HID. It is not normally the bulb, but the transformer unit. Details in the link.

Yes, it CAN be done without pulling the bumper, fender and entire headlight assembly.

I just completed a HID bulb replacement on my 02 SC430. Took about two hours and included a copious amount of swearing. It is a PITB process that is largely done by braille. Sausage fingered individuals should not even try. The clearance is very small - just enough to get your hand into position.

if you google search agains "sc430 headlight service manual" you will find a pdf of the headlight service procedure. I largely followed those instructions, but I have a few hints...

1. Do the passenger side first. Removing the air cleaner gives you some ability to see what you are doing. That lets you learn the process before you go do the driver side "blind".

2. The service manual did not mention a few wires that are present. The leads for the amber indicator light stretches tight across the HID moisture cap. You need to pull the amber indicator bulb assembly first. Fortunately, that is a simple twist and pull. Once the amber lamp was free, I disconnected its harness and set the bulb aside in a safe location.

2b. A pair of wires were physically attached to the HID cover. These make it extremely difficult to maneuver the cover, particularly when putting the cover back on. I ended up physically detaching those wires from the cover permanently. Made life a lot easier and will make replacing the HID bulbs simpler next time.

3. The HID bulb socket easily detaches. The wire spring bale is hinged and won't fly away when you get the two ends free. Those are freed with a squeeze and pull movement. You can do one side at a time.

4. Make certain the spring bale is swung out so it does not impeded placement of the new HID bulb.

5. Because you are doing most of the bulb insertion blind, it is difficult to avoid touching the quartz jacket to something. Practice with the old bulb first. Once in place, you gently rotate the bulb until its notches allow it to seat. You can feel that pretty easily.

I used the "MAXLUX HID Xenon Bulb D2C (D2S/D2R) 5000K" bulbs obtained via amazon. Yes, that price is indeed for a PAIR of bulbs. I thought it was for a single bulb due to the low price and ended up with four bulbs.

The new bulbs light up much brighter than my aging 02 HID bulbs. A slight bluer than the OEM Lexus bulbs, roughly the same color as the HID's on the Aston. Longevity is, of course, yet to be evaluated.

Success. It can be done, but I guarantee a lot of colorful language during the process.

unless they are seperate,you dont,if they are seperate,there is a screw on the bottom and side from the front that you can turn

Check the HID ballast. Make sure the ballast is not blown.

If fuses are good, most likely the 'ballast' is at fault.

yup you have a loose ground I have to agree .

To wire up an HID kit on the low beams of your Mazda 3 2005, you will need 3-4 things:
1- HID kit (bulbs and ballasts)
2- HID relay (connects your hid kit to your battery)
3- 4700uF capacitor (solves DRL flickering issue)
4- H7 hid bulb adaptor (you can also use the rubber piece that holds the bulb wires as a spacer)


Wiring diagram:

Tips on How to wire up:
1. HID bulb's amp wires connects with the ballast's amp wires. (There's only one way to connect them.)
2. The positive and the negative spade connectors from the hid relay connect with your vehicle's low beam connector, closest to your battery: the driver side. The passenger side low beam connector is not used and should be insulated. You can use electric tape.)
3. Each ballast is connected to one of the relay's clip connector, and it's grounded on each side to your vehicle's body. (One connector for each ballast, one for each side. You can use the screw for the body as a ground.)
4. The red wire(with the inline fuse) in the relay connects to your battery's positive terminal.
5. The capacitor sits on the relay switch. (Google for how to wire the capacitor onto the hid relay switch.) dynoxg image
6. The halogen bulb sits on an adapter. You can safely remove them from each other, and use an H7 hid adapter instead.

wow and I thought bulbs were getting expensive!! Try an aftermarket headlamp assembly. The best bet is to research on line.

I have a 2005 Lexus Rx330 with HID AFS headlight. My passenger side light went out. I thought the bulb burnt out, so I bought a new bulb. After replacing the new bulb, it happened exactly like my old bulb. It light up lightly and then total black out. What's wrong with it? I thought the ballast burnt. I called Lexus dealer and asked for the new ballast/transformer. Surprised me, they don't know what is it. They told me they only know the wiring harness and the socket, but not the ballast ??????? Could you tell me what do I need to replace?

Thanks,

It's the Ballast. You have to pull the front bumper off to get at it. It's about $100 for the part. Good luck
