Looks like "white" led bulbs. I have led bulbs in mine, and it looks identical.
I simply got mine of ebay. But you can get them anywhere. One tip though, do NOT cheap out. Make sure there are lots of leds on the 'bulb', you want it to be nice and bright.

 

Here in Australia it is totally illegal to drive with your fog lights and headlights on at the same time. You can cop a fine and loss of points on your license. A policeman down my way loves booking people for that offence. its is basically the same offence as failing to dip headlights.
Fog lights are only to be used when it is foggy or raining but not in conjunction with headlights. If you dont have fog lights then headlights have to be used or cop a fine. Not a very well known law but easily verifiable. Ignorance is deemed not to be an excuse. Basically they have to be switched separatly in Aus

 

Quite a few cars with HID lights use the fog lights as daytime running lights from the factory. So its not illegal, it just shouldn't be tied to parking lights (it should be on when you release the handbrake).
