Has the front fog just blown a lamp or do you need a complete housing ?
If its just the lamp, you can get one off eBay of from Amy auto spares, you need a h11 lamp.
You can also pick up complete fog housings for around £40
And the tailgate brake light, unusual for that to break, as the unit is sealed you will have to change the whole unit
Britpart sells these for around £60
Hope that helps
