I will give my contribution with the headlights: I bought my 3W in the UK and moved it to Italy, I needed the LHD headlights to get it registered: MCC was charging 288 GBP + shipping, but I bought the correct headlights from Wipac's website (just go to the Aftermarket section) for 54 GBP (total for both lights). MCC was insisting that I had to change the whole headlight assembly, when in fact I changed only the sealed beam unit and that's enough. The headlight is a standard 7" unit with the sidelight, I installed them in 5 minutes with no electric work needed. i hope this helps.
