White, LOL!
Actually, you need to be careful about that as they are doing some sort of price update and their database is all screwed up and it might cost you $30 bucks, as almost happened to me a few weeks ago!
Just go to the display rack and look them over with my above specs (and make sure you pay attention to match the relay posts and numbers!) and get that one. In the package description they will also mention that it has burned out signal bulb ability. Which you want.
These flasher relays are a real standard part, but there are about a dozen to chose from to fit all vehicles and options so you can't just grab any old one.
