Well, in the process of putting in a new handle today, they work!!
I tested the wiring for voltage, and it had 12 volts.
Hooked the original light backup, nothing. Swapped bulbs... nothing. Swapped handles, and it works.
So I go to the driver side handle, pop the cover off, test it, has good voltage. Stick my small screwdriver in to pop out the bulb, and it suddenly pops on. WTF... I jiggle the bulb, doesn't go out. OK. I put some dielectric grease on the ends, popped the covers back on and went on my merrily lit way.
