I wandered if any one can help, I have a 1939 m23 and am lucky enough to have the map/ inspection lamp with it as fitted to the tank top instrumentpanel. I have now got it working having managed to solder wire to the existing little bits of wire on the contacts.( quite a challenge) It all tests fine, but does anyone know what type of bulb this takes, seems as though it has a long section from where the bayonet pins locate to a contact at base of the switch . And any ideas if these are available. Many thanks in anticipation for any help, Dave
Dave I have tank top insterment panel original bulb that came out says "british made 5v-3w" another same size says "mazda bth 98 6v 3w" one I have in bike now that I got from local supplier in US says"wagner china no#s" 6v silver base and fit. this might help Charlie
Thank you for your help, l think there is some in internal bulb holder/ contact missing on mine but if yours is brass like mine may l ask if you could send a photo please to see what might be missing? Many thanks
