Hi all - I am a new member - though I've been a collector for about 30 years! I have kind of re-discovered my hobby recently and decided to start cataloging. My problem is with a Mazda bulb marked as 115v 20w 995-5222(4?) for which I cannot find any information anywhere (well, not on Google anyway!!) It is 75mm x 25mm with a bayonet cap. Any ideas from anyone else in lamp-land?! Thanks, Dave.
