not sure they have made leds in the correct format bulb equivalent bob
to be honest I found a couple of reasonably high powered leds and just silicone them into the breather holes , either side of the main incandescent globe holder ...of corse the leds were not rated for 12 volts ...so had to install a current limit resistor in line ith the posative of the power feed ..... i had series up the leds and found that about 330 ohms resistor kept the current through the leds under 20 milliamps

worthy of a mention is that the high powered leds do have a rather narrow light beam rather than the spread of an incandescent globe , additionally there isn't much distance between the back of the instruments (where the leds may be fitted ) and the backing plate - scale face of the instruments
so if you can find a wide angle 3mm led suitable ….in the 10 mm types you an find the inverted focus type ...like this

….. which gives a pretty reasonable spread of beam of light ...rather than the dome type (concentrated focus ) types
you might be looking for at least 5000 milli candela 3 mm leds to do the job , with either flat or inverted type lens out the front ...no that I have seen any such a beast as yet ...but I haven't been looking in the last year or so for useful version ...but will be chasing up some in the coming year for the project im currently working on
