yes mate thats for the whole lot, you can get just the glass, they are around 25 quid each but i cant remember where they can be had, its not the dealer was somewhere else, will come back to me, i do know its almost impossible to swap the lenses without breaking them on the rears, and they never seal correct one they have been in bits (did a mates, was a nightmare)
you might be best off going for the ones in ther ebay link posted above, the seller has just the fogs (complete) for 59 quid... thats not bad for the full unit
