If it's the taillight you're talking about, yes that's the correct number. you can find a complete list here:

As for those two LED's you found. I would go with the second one, looks like a sturdy base. However, if you still have you're stock taillights, and you put them in there, the lens itself is red, so it would look like a purple light. If you're going to put them in the front, it would look greenish, unless you cleared out the headlights. You might want to also check the legality of such items in your area. You could probably call the local courthouse and get the number for the department of motor vehicles and askthem.
