dash indicator light bulb

would anyone know if it is possible to get the ultra small light bulb for the dash left and right indicator lights that fits into the dash of a Bedford bus.
It is held in by the little red lense that screws in to the socket . I found a lucas number on page 42 of a downloaded catalogue, but it is only for business importers. Maybe some Aussie retailer will have them.
The number is LLB280 24v 3w X .75mm total length is 21mm base is MCC Ba7s ..Colin

Have you tried instrument/gauge repair shops?

If it any help many British cars also used them.

I have managed to lose one from my 1954 Singer and about to contact the Singer Club to source one.

You mught like to try also.

Commodores and Land Rovers use them too, $2 from any auto sparkie.
