You might not be quite so lucky as to fit a standard bulb.
I've a nice Specialized Solo NiCad made by NiteRider. The bulb unit is an NR11 as opposed to standard MR11 - it is 6V and has an lens fixed to the front which makes it a bit thicker, important for fitting the front plate of the lamp unit and sealing the electrical gubbins from the elements.
The NiteRider importer were fine about supplying a replacement at under £25, 4 years ago.
