I notice some Prius are using white light beans. Are those LED light bulbs? If so, where can I find them? I search eBay and I do not find any.
You would have a very difficult time trying to purchase and install the LED headlight assembly into your car. If you want a whiter light the easiest method is to purchase an HID kit from TheRetrofitsource.com or DDM Tuning and install that into your factory halogen projectors. Just don't buy anything higher than a 5000k rating or we will make fun of you.
