When I purchased my FRS it already had a Kensun HID lights installed.

The passenger side light has died and needs to be replaced. Is their any way of telling the Kelvins of the bulb? Where is the best place to purchase replacements? I have seen them on Walmart's website.
This is the spec that I have found that best fits what I think I need as a replacement part:
Kensun UN-K-55W Bulbs-H11-5K HID Xenon 5000K 55W AC Bulbs, Pure White
found on the Walmart wesbite.
