Also, if you remove the little green plastic covers where the lights go it will be even more bright. You will lose the green effect unless you picked up the green lights. I have pictures of the difference, but it's even more bright and clear in person, but don't be fooled! It's not so bright it blinds you at night.
And then these for your dummy lights. (red for red dummy lights, etc)

I think the turn signal indicators on certain dashboards are a different type of bulb instead of the wedge based ones, I'd need to see what they were before being able to tell you which ones to grab.
