Identify these lights

My guess is the long thin lamps on left are CCFLs.  And the lights on the right are fuse lamp bulbs as they look like they snap into a fuse-holder?

JKL sells both styles.  The CCFL bulbs operate at hundreds of volts (albeit at low currents) and require an inverter to step up, say, 12V DC.  My guess is that's what's in the black heat-shrinked package.  Not sure why there are two "styles" of lights in the roundhouse but both types have been supplanted by LED versions in the same/similar packages.

Since it appears you are already performing surgery to fit your particular layout, I suggest replacing those lights with 12V LED strips which are inexpensive (say, $5-10 to replace what you are showing) and have been widely discussed on OGR so plenty of help here if you need it...

Thanks stan.  I tried to power up the fuse lights with both ac and dc up to 12 v, no joy.  I haven't tried to power the longer ones.  There are still fuse lights glued to the roof of the remaining three stalls, I'm going to leave them in place and go with your suggestion of led's. 

Update, i cut the wires on the longer lights and connected them to a 9v battery, they lit up but clearly needed more than the battery could provide, these will be tossed. 

Using the same 9v battery i learning some of the "fuse" lights were blown along with one of the wiring harnesses not working at all.   Of the 12 installed, 8 worked.  The six that are still in the repaired 3 stall roundhouse work so i will leave them and supplement with lighting. 

The structure is brittle, whatever glue was used is far stronger than the walls and roof, i think the less is more approach applies here.
