Fog Light Bulbs

Need a new front fog light bulb - what the hell am I after :confused: (do I just ask for a front fog light bulb or do I need a specific type with whatever voltage/wattage) and how much?

Haven't got a clue when it comes to anything like this, searched a few threads and its all like a foreign langauge to me

Out of interest are there any better ones I could upgrade to? Again what would I be after and how much?

Also both lamps appear to have condensation in them after driving in all the rain etc... is this a problem that can be solved when I replace the bulb(s)?

Any advice and guidance appreciated !!
