I'm looking at doing this - I have a set of 50W H3 HID lamps/ballasts/igniters (from Colebatch), and have just bought a 2nd hand set of Micro DE's.
I have the Touratech version on my 1200GS (basically standard Micro DE's with the addition of an aluminium 'cover') and wanted a 2nd set so that I can rig them up on the bench while leaving the existing ones on the bike.
I'll advise on progress - might take a couple of weeks though!
