The bulb is only listed in the parts catalogues with the black molded plastic bulb holder so maybe it can't be replaced? Or maybe you can just pull it out with a bit more force than I've wanted to apply for the moment?
Here is a pic of the lighter and also of the bulb holder with the little bulb in it. I can get a whole new lighter on ebay for about a tenner but I'd like to just change the bulb.
Thanks for any help!
