| I bought a couple from a normal electrical shop, the one in Stromness if I recall correctly. Can't remember if it was £2 each or £2 for a pair. They may not be exactly the right spec, but first one's still running 2 years later.
The ones without glass are harder to get but easier to fit. With glass, you need to get hold of a kid's arrow with sucker, or a valve grinder thingy (sucker) from Halfords. Not used the with-glass type, so it's conceivable they could overheat, but I doubt it.
The big advantage of the Pro-head is it takes normal domestic 12V halogens, just like the ones in B&Q etc, bearing in mind glass or no-glass.
