I do have one round style Soubitez, but it is part of a set with a bullet head light, don't really want to break the set. Not too many mom and pop stores left around here, they have been dropping like flies. Went to where my local hardware store was yesterday...key word was. I was in there back in December and now they are gone. Next nearest store is 20+ miles away.

I will start trolling the "bay" and see what pops up. I am still a bit puzzled by the tail light on my Superbe being a push in style bulb, that would have been fairly new technology at that point and I just can't see Raleigh doing that.

I do have a few other bikes I can try the bulbs out on that use the screw base, two of them use the Union/B&M style fender mount, another is a Peugeot with a fender mount and the Columbia has a JOS.
