I am trying to remember what I bought, I believe they were made by Philips. I got them off ebay of all places for less than $100. I think they were 60 something lol. Replace them in pairs. I searched this site to figure out what I needed. Oh and it's xenon. Try searching I'm sure the model number is here. Hope this helps at least a little.
Just remembered that stock is 4300K which is what I replaced mine with.
