are the B-pillar lights on an 89 brougham d'elegance supposed to light up, or would i have to modify them to do so?

As far as I am aware the transformer is actually the more reliable part. The electroluminescent paper that was used is easily destroyed by UV rays and because GM was retarded in the 80's they never put a UV coating on them.
Try and find good ones. These things were not designed to be fixed, they are sealed shut. You can buy EL tape on the internet in several places now but you will have to cut open the lights somehow to replace it.
Test it. Take a voltmeter and measure the power coming out of the inverter. It should be around 110V AC. The inverters do go bad but the lights themselves are most likely toast as well, especially if the car sat outside for any length of time. I have working lights on my '88 but the inverter went out a few months ago and I have yet to find a good one. The inverter is just as hard to find as the lights themselves (took me almost a year to find working lights for it).
LEDs may be hard to fit in there. The distance between the lens of the light and the housing is only like a 10th of an inch, which is what makes them flush to the body and why they used the paper in the first place. Also, the paper produces a very pleasing light that does not violate any state codes. It is very soft, soothing, and evenly spread light.

On the other hand, LEDs produce a rather harsh and bright light. They can be dimmed but it is unlikly that you will get as even of a light pattern as what you get with the paper. Here are pictures of both my '88 and my '90. Unfortunately the inverter on my '88 took a dump at the end of last year so if anybody can get me a working one I would pay you handsomely.
