I've just purchased a few (not too pricey) GU5.3 LED bulbs to replace my
low voltage lamps in my stairway.

On connecting and switching on the bulb flashes then goes out, if I
switch off then back on it again flashes.

Is this likely to be a transformer problem, unfortunately due to a
building extension each of 5 lamps on my stairway have a separate
transformer and it would be very difficult to rewire each into a new
transformer.

Any ideas appreciated.

Probably below minimum load on the trafo, usually 10 or 20 W.

Looks like you`ll have to look at the wiring fishing thread from a
while back.
