Ha ! £37.60 with a 10% discount for me. They're removing it now and I'll be using the spare one I had from eBay 6months ago (£18 for 2 bulbs).
I wouldnt mind if it lastest twice or three times as long as a normal (cheaper) one but this has gone after 15months and 22k miles.......not good.
Mind you....they've done a hell a lot of work on the bike under warranty......I felt quite cheap taking up there offer of taking it out......but I'm over that now !
