After a quick search, looks like they're the same size bulb. Just get a good brand, it should have little built in fans, like a Sylvania. Stick to your 9006, or whatever size it calls for. Sylvania is nice, I bought them for my (now ex) girlfriend, she loved them and helped her see better at night. Trust me, don't get cheap ones, its the stingy man who spends the most.

Note: I think its technically illegal to go from halogen to LED, ive never heard of anyone having an issue. But if you're from a super crazy place they may fail you for an inspection, or if the local police are on some LED light crack down lol. But again I havent met anyone who had an issue with that.
