I already have some traffic light models but they don't have animations. I cannot figured out how to animate the model to make the color change. I'm really a noob in model making in MED.

If someone is kind enough to share or better yet animate this model. Just 3 frames of animation is enough. The frame 1 is for red and then next is yellow then green. Then I really be thankful because It's a big help for my simple car game.

here's the link...

Hoping for someone to lend a hand. Thanks!
