Hello All.

I'm in the process of replacing my HID bulbs and I've decided to replace the ballast as well.
I need help in selecting a ballast.

I purchased a 5k D4S 35W Bulb from KBCarstuff.com/Xenondepot.
The very nice tech told me that they don't have the correct adapters for the ballasts they have to fit the bulbs I had purchased.(I decided to replace the ballasts AFTER I received the bulbs already, doh!). I found that a little odd, but I took his word for it.

So,

1. Where can I buy a ballast that can fit the bulbs that I've purchased.
2. What are the differences between the different ballasts. Is it just size or are there technical aspects to consider?

2007 IS350.

Thanks in advance!

 

Sounds like they are confused.

If you car came with factory HID's the D4S will fit fine.

Now, if your car did not come with factory HID's and was modified to have aftermarket HID's, that is a different story.

 

Why do you want to replace the ballast as well? If its working fine, theres no need to replace it.

This. No need to replace the ballasts if they aren't bad...

 

why replace your OEM ballast when there's nothing wrong with it???

 

thanks for the replies so far.

a little more info on my siutation.
my car was involved in a major fender bender whereby the entire driver side front fender/bumper needed to be replaced. this included the entire headlight assembly.

4 years later, my OEM HID bulb turns on initially, but will go out after a short period of driving. Usually about 15-20".

I think the ballast may be bad if the light turns on, but goes out after a while.
I suspect the repair shop may have used the original ballast that may have been damaged in the accident? I don't know, but I would rather take care of this problem once and for all if I'm going to replace the bulbs.

does that make more sense now?

 

It's the bulb most likely that is bad. I've had the same issues and only when I changed to Phillips (I bough ultinons from xenon depot) did they work consistently.

The cheaper bulbs don't like our hid systems and wear out super quickly

 

Added post - I know you have an oem bulb but maybe it's time it's done. No point in paying for ballasts might as well buy some reputable Phillips bulbs and see if that fixes it.

 

If the ballast was bad, the light wouldn't turn on at all I'm pretty sure.

 

Get new bulbs first and see if thats the issue. Dont assume that its the ballast

 

Swap the bulbs from passenger to driver. If the problem changes sides, you know it's the bulb. If problem remains on the same side, it's the ballast. But most likely it's the bulb.

 

Hi,

I'm not sure if there was some confusion when you called but we do not carry aftermarket or OE D4S ballasts.

Were you having the same issue before you installed our d4 bulbs? We have not had any issues with the XenonDepot D4S bulbs or the Philips D4S bulbs as the quality is quite similar.

Whew. I finally got around to installing those bulbs! It's been a crazy busy month for me at work and in life with the holidays, etc.

You all were right.. It was the bulbs that were the problem and not the ballasts.
Now that I've replaced the bulbs, I'm no longer having the light going off issue.

Upon removal of the problem bulb, it looked like the filament had been bent. I wonder if the repair shop tried to reuse my old bulb from the crash rather than buying a new bulb?

Thanks for all the help.

Does anyone know where to buy additional plugs that hold the engine cover in place?
I think I broke several of them. I had a lot of mismatches. LIkely due to the repair shop that
fixed my car after the big crash.

 

The push in clips?

You can get them from Sewell or eBay
