Litronics for continental use - cayenne?

[nukem]

Help! Currently in Europe with our Cayenne. My wife came out early, and I told her to get her dad to read the manual and convert the lights when they got here. I flew in last night to be told it's not in the manual. I was under the impression that to convert Litronics for European use was a simple matter - throwing a lever I thought. I have read the manual, but it says to buy the eye patch kit from my local stealer. Did I imagine this, or am I confusing it with my Boxster? Surely it is possible?
Advice gratefully received.(but not"don't drive at night"!!
Thanks
Phil
