K-Line streamlighting bulb replacement

I recently acquired a new-in-the-box K-Line Bunk Car with smoke, stream-lighting, full interior and figures.  The interior lights do not work and, upon dismantling the car, I found that one of the bulbs has a broken lead and needs to be replaced.  Just my luck in that it is located close to the smoke unit!  I have read that these bulbs glued in.  Are they easy to replace?  The car came with 2 replacement bulbs.  Any and all suggestions graciously accepted.
