Since you don't have stock wiring (I'm assuming), you'd do better to be creative and mount something there that works better. Bosch Compact 100s or Hella Micro DEs come to mind for inexpensive options that work well; Rigid Industries Dually D2s are tooting my whistle for a bit more money but very interesting.
The stock '10 foglights are 24 watt show bulbs. The '07-'09 are 45 watt.
An H4 headlight upgrade from Daniel Stern Lighting would mitigate the need for foglights to begin with; then you could use those holes for some floods for trail use or drivers for supplements to your highbeams.
