We got a 2009 Forester a couple weeks ago.  I bought the fog light kit from Subaru.
Today, I installed the fog light kit on the 09 Forester.
Good parts- kit came with everything needed, including a new lever with the switch for the fog lights, and installed easy.  Relay just plugged into an existing socket.

Bad parts - have to remove the entire front plastic "bumper" & grille piece to install the lights.  Aiming is a pain, since the adjuster screw is in the back, and all the covers get in the way.

But the dumbest thing, is the way the switches control the lights.  Grrr.  All of my older Subarus have the headlights shut off if the ignition is switched off, so you cannot accidentally leave the lights on and kill the battery while parked.  STUPID CHANGE.

The Fog lights only light when the headlights are on.  OK for helping in rain and other situations, but when you need fog lights the most - in heavy fog or snow - you actually want the headlights OFF.
Grrr.  Stupid design.

How much was the kit?

It was a little over 300.00. It was really nice not to have to do any customizing just to put them in, and it all went smoothly.

I got it from one of the online discount Subaru parts dealers . I did have to clean the contacts on the lamp connectors. Put a tiny bit of copper antisieze on them too.
