I need a 12 - 14v MES dimple bulb.

What's a 'dimple bulb'? Do you mean one with a lens? In which case an
LED bulb would be a good alternative.

Very common in the US, but unheard
of here (unless you know better?), and postage is a killer.

I have a blown bulb, and can probably get the glass out of the base, but
can I cut the base of the glass?Â* Thinking if I could cut the glass, I
could insert a grain of wheat bulb, which will do the job, but how to
cut the glass?

Standard MES bulb uses a ceramic cement to 'glue' the glass envelope
into the base.
