If your problem is the bulb itself has gone bad, then yes buy new bulbs from The Retrofit Source. If your problem is a bad ballast, then you might want to consider buying one of the aftermarket 'kits' from them. I can't be certain, but I think I have seen other members here reporting that factory ballasts cannot be replaced and you must buy the whole headlamp assembly or use an after market kit. That info needs to be verified as my memory might be wrong.Wangtang408 wrote: ↑Tue Jul 25, 2017 6:05 pmMy car has the factory HID, can I buy bulbs as mentioned above or do I have to replace the factory ballast ?

Seems like TRS isn't as honest/good as I thought. They are fibbing their product information. Their customer service is excellent, still, but their ability to 'upsell' by making stuff up is just as good it seems lol.
There is no discernible difference between the Osram Xenarc Night Breaker (4350k), Osram Xenarc 66240 CBI (5,500k) or the Osram Xenarc 66240 CBH (6,000k). They are ALL rated at 3200 lumens directly from Osrams data sheets. So the TRS numbers of 3,500lm and 3,600lm for the CBI and CBH, respectively, is a bunch of BS.
So here's a little chart (sorted by brand):
Sorted by lumens at 35w:
Keep in mind that Morimoto seems to be the TRS "house brand" so their data might not be accurate (I say that because Morimoto's website looks verrrryyyy similar to TRS's so either they hired the same developer, or they are owned by the same people).
