Again, thanks for all the help and advise. I was able to purchase a new Xenon Strobe Tube for $4.09 from Radio Shack #272-1145 right off the shelf that fits and works well to repair my old light. The same type of bulb is available through Actron for $2.59, but they only ship Fed Ex, which would have run me an additional $27.00+, being in Alaska. Not a very good deal with the shipping, obviously. You might want to jot that Radio Shack tube number down for future reference. On re-bay I found a new in box Actron CP7504 Inductive Timing Light for a total of less than $12.00, including shipping. The Kal Equip, SunPro, Snap-On, Sears, Penske and Mac lights sold for much more, but the $50.00 Actron, most people don't know that Actron is the parent company of SunPro as well as Kal Equipment, so there were only two bidders. Something to keep in mind.
