Sun Lamp casting light in the opposite direction it's facing?

This is before I start the game engine: (so in object editor mode)

I have a sun pointing to the front of player, but it lights up the back.
Shines correctly after I press ‘P’ to start the game engine though.

Did I hit something by accident? Using 2.72
Not a huge deal, but have had this happen before. Any ideas?

Thanks!

Flip the normals of the mesh around.

Darn it… shoulda known.

Rookie mistake. Thanks for the help x[
